INTRODUCTION
Congratulations
At TC Electronic we are more than proud to present the new G-System that will be the center of your guitar setup in years
to come. Presenting a new piece of equipment to guitarists is always exiting due to the very different demands they have.
As you know, guitar gear is not comparable to “just a new keyboard with better sound” or “just a slightly better
microphone”. Just think about it: Do you know anyone who has a guitar setup 100% identical to your own? Most likely not!
Bearing that in mind, the task of building a piece of equipment like the G-System has been a tremendous challenge, well
received by the entire dedicated staff at TC Electronic.
Utilizing the experience we have gained with its successful predecessors – the G-Force and the G-Major – and from the
vast input and response we have received over the years from our customers, the G-System was born.
Features
• Floor-based Multi-effects processor.
• Up to 9 effects can be used simultaneously.
• Fast and smooth preset changes featuring Delay spill-overs.
• 4 switchable mono-loops for integration of your favorite effect pedals.
• 1 additional loop/insert point dedicated for pre-amps.
• 4 x 9V DC outlets powering your effect pedals.
• USB connector for software updates.
• Ultimate flexibility as the Control Board can be separated from the
GFX01. This allows you to place the GFX01 with loops etc. in a 19" rack
while leaving the Control Board on the floor.
• MIDI for control of additional external MIDI units.
• Connectors for 2/4 expression pedals.
Should this manual leave any of your questions
unanswered, please use the TC Support service, which
you can access via our website www.tcelectronic.com.
Over a period of time, we will collect the most frequently
asked questions and update the manual accordingly.
Manual updates are available for download on our
website in PDF format. The current manual revision
number is found at the bottom of page 3.

INTRODUCTION
Once you are up and running …
… what can you do?
How you get where you want to go is explained in later
chapters in this manual – this section is only meant to
serve as an inspiration while you are getting ready for
building your dream setup.
The Five PRESET and BANK UP/DOWN Switches
Presets are organized in banks of five. Using the five
PRESET switches together with the bank UP/DOWN
switches allows you to make radical changes to your
sound by pressing a single switch.
Preset Switches
Presets consist of:
– Effect Blocks (Reverb, Delay etc.) – both active and
inactive ones.
– Settings for all Effect Blocks – for both active and
inactive ones.
– Status (active/inactive) for all loops.
– The assignment of the connected expression pedals.
– Various other parameters.
The EFFECT BYPASS & LOOP Switches
These switches allow you to turn effects (such as Delay,
Reverb, Pitch, Modulation Filter, Compression and the
Loops) on or off as parts of a presets. These switches
are similar to the On/Off switches on regular stompboxes.
6
Three, four or five Loops
There are four loops – for drive pedals etc. – plus the
Insert loop, which is especially designed to insert a preamp. For each preset you can decide which of the five
loops should be active.
Additionally, you can switch loops 1 to 3 on and off using
the Control board. If you also want to have access to the
fourth loop via the board and maybe even to the Insert
loop of a pre-amp (or a fifth pedal), you can set up your
switches accordingly using the “Custom Switch
Functions”.
What? How? Why?
You may find your own way of utilizing the system, but
the following describes part of the philosophy that has
been the basis of the G-System’s design.
For the purpose of the following example, let us assume
that you have connected overdrive pedals to some or all
of the four loops and maybe a pre-amp to the Insert loop.
Expression pedals are excellent for either Volume control
or real-time parameter control such as pitch in a
“whammy” effect.
For the following example, your setup should resemble
this one:
INTRODUCTION
•
Use presets to organize you basic sounds. Presets
are recalled using switches 1-5.
Example:
1
2
3
4
5
Rhythm 1
Rhythm 2
Crunch
Dist
Lead
Note that these names are just suggestions – this is not
an actual set of presets. It is up to you how to benefit
from the G-System’s flexibility.
If you need more than five presets, simply press BANK
UP and use another five. You have access to up to 40
banks with five presets each.
•
•
•
Each G-System sound (preset) stores which loops
and effect blocks are active and which parameters
the expression pedals control.
Presets hold all settings for all effect blocks – both
the ones that are active in the preset and those that are
not.
Settings are stored both for active and inactive
effects.
Once you have a basic set of presets such as the one
above, you can switch between them in the different
parts of a song using the preset switches. In addition,
you can activate/ deactivate Effect Blocks within presets
using the Effect On/Off switches. You can also
activate/deactivate Loops 1 to 3 as desired.
Example: You may start out your solo with a lead sound
with a bit of Reverb, but as it evolves you may feel like
adding some Delay, a Panner, an Octaver or maybe
boosting the level using the BOOST switch.
Note that these are just ideas – it is up to you to explore
the G-System’s potential.
Custom Switch Functions
After some time, you may want to customize your
setup.
For example, you may not be happy with the way the
switches are positioned on the board.
You may want to access all five loops using the
switches.
You may require eight preset switches, but you could
e.g. live without bypass switches for FILTER, COMP
and PITCH.
Go ahead! The G-System’s board layout is a default
suggestion based on input from numerous guitar players
we have talked to.
You can customize this layout to your liking, making each
switch do exactly what you want it to.*
To customize switch layout, press EDIT, press MENU
and go to “Switches”.
* Please note that the EDIT switch and the UP/DOWN switches can not
be reassigned to other functions!

QUICK SETUP GUIDE
This Quick Setup Guide will help you get started if you already have a basic idea of how you would like to use the GSystem. If you are new to the world of multi-effect processors, you may feel that you need some more “in-depth”
information. In that case, please refer to the relevant chapters of this manual. You may find the “Overview” section (pages
14 to 21) showing connectors, switches and encoders especially useful.
Unpacking
•
Open the box. Be careful not to damage the items
within the box with sharp objects, such as knives or
scissors.
• Make sure that the package contains the following
items:
– G-System
– Users Manual
– Power cord
– CAT5 cable
– 4 x 50cm power cables for pedals
– Labels for switches
– Product registration card.
Register you G-System either by sending in the
registration card or via www.tcelectronic.com.
Rackmount or Floormount?
Right out of the box, the entire G-System is assembled
as one floormount unit. But check this out …
The G-System consists of two main parts.
1) The Control Board – this is the board itself with the
1/4" stereo jack connectors for expression pedals and
the RJ45 connector for the GFX01.
2) The GFX01 – this is the 19" rack unit that contains
the signal processing unit, connectors for loops, the
power supply etc.
Per default, the two units are assembled as an “all-inone” floor processor. However, if you wish to have all
loop connectors to your pedals and e.g. a pre-amp neatly
packed away in a 19" rack instead of spreading them all
over the floor, you can easily detach the Control Board
from the GFX01 and mount the GFX01 in your rack. For
more details on the this procedure, please refer to the
“Connections – Rackmount” section on the following
pages.
Connections – Floormount
Now let us connect your G-System. We assume that you
are using the G-System as one floormount unit – as it
was assembled in the factory.
Let’s take a look at the rear panel of the GFX01.
Input Instrument
• Connect your guitar to the socket labeled “Input
Instrument”.
8
QUICK SETUP GUIDE
You must decide whether you use the Input on the
front or on the rear of the GFX01. This is
configured using the Input Select parameter in the
Global (Glb) Levels menu.
•
Be sure to activate all the pedals that you have
connected in the loops.
•
If your pedals require a 9V DC power supply, the GSystem provides 4 x 9V DC outlets (max 200mA
combined), so you won’t need an external powersupply.
Loops 1 to 4 and Insert
• Connect up to four Overdrive/Distortion pedals – or
other mono effects – to the G-System’s four loops.
Connect “Send” to the pedal’s Input and connect the
pedal’s Output to “Return”.
•
If you also wish to connect a pre-amp, use the Insert
loop. Connect the G-System’s “Insert Send” to the
pre-amp's input and connect the pre-amp's output to
“Insert Return”. Alternatively, a fifth stomp-box pedal
can be used in the Insert loop.
If you are in doubt as to which type of power your pedals
require, you should consult the documentation that came
with the pedal. On some pedals there is also a small
label next to the power inlet, which you should check.
We are quite confident that once you have become
familiar with the G-System, you will find that it is both
easy to set up and customize. On the other hand, the
flexibility the G-System offers means that it comes with a
wealth of features that you may not want to utilize right
away. You may also come across features that you didn’t
know you needed – until now!
9
QUICK SETUP GUIDE
Connections – Rackmount
As previously mentioned, the G-System can be
separated into the Control Board and the 19" unit called
GFX01. To detach the GFX01, simply unscrew the four
rack mounting screws.
The GFX01’s mounting screws are 6mm in
diameter. However, some rackmount units require
5mm screws. Use appropriate screws!
To ensure maximum stability, a blank 19" faceplate
must be mounted instead of the GFX01 after it
has been removed from the Control Board.
•
•
•
•
Connect pedals and pre-amps in the same way as
described in the previous section for floormount
operation.
Once separated, connect the GFX01 and the Control
Board using a long Cat 5 cable (not included).
Connect the Guitar to “Input Instrument”.
Levels
Set your drive pedals and the pre-amp to “reasonable”
levels. Setting levels to maximum may cause internal
overload, resulting in clicks and unwanted digital
distortion.
When the red OVERLOAD LED on the INPUT meter
lights up, the signal is too hot.
Not Good
Good
Overload LED
To avoid having to run long cables from your
expression pedals to your rack, the Control Board is
equipped with duplicates of the two Expression Pedal
connectors found on the GFX01.
Depending on how the Input gain is set on the
G-System, you may slightly have to adjust your
drive settings on pedals and pre-amp when these
are connected using the G-System loops.

QUICK SETUP GUIDE
Presets
•
•
•
The G-System holds 100 Factory presets.
You can store up to 200 User presets.
Presets are organized in banks of five.
“A0” to “A9” and
“B0” to “B9”
Each Factory bank holds five presets “1” to “5”
To
•

Recalling (Loading) a Preset
• Recall a preset by pressing one of the PRESET
switches (1-5). You select a preset bank using the UP
and DOWN switches.
• Press both the UP and DOWN switch to quickly
switch between the Factory and the User bank.
Effects that have a switch assigned to them can also be
toggled on/off via the corresponding switch.
Loop 4, the Insert loop and effects that per default
have no dedicated switches are accessed from
Edit Mode.
Storing (Saving) Presets
To keep the changes you have made to a preset, the
preset must be stored in the User bank.
•

QUICK SETUP GUIDE
Other Important Issues
The following is a list of other important issues you
should take care of when setting up your system. Please
refer to the relevant sections of this manual. Use the
Table of Contents (page 3) for directions.
Read the Section “Setup Examples”
The “Setup Examples” sections gives a good overview of
how the G-System can be connected to the rest of your
gear.
Use correct cables for …
- Loops 1 to 4
- the Insert loop
- Expression pedals
Calibrate your expression pedals
Expression pedals must be calibrated for best
performance.
Make good use of the Boost feature
You can set a boost level in each preset and activate it
using the BOOST switch.
Use the Locking functions to protect settings
-
-
Lock the Insert loops if you have a pre-amp
connected in that loop and wish to use the pre-amp in
all presets.
Lock the Boost level to have the exact same boost
level in all presets.
Lock the EQ section if you use the same EQ in all
presets (i.e., as a “master EQ”).
Lock Relays to keep the same relay settings
regardless of how the relays are set in presets.
Lock the Routing type if you only need to use one
routing.
All Locking functions are located in the Utility menu.
12
Get the most out of your amp(s)
using switch options
You can switch channels on your amp using the GSystem’s four relays. Of course, these settings can also
be stored as parts of presets.
Input Select
You must decide whether you want to use the Input on
the front or on the rear of the GFX01. This is configured
using the Input Select parameter in the Global (Glb)

OVERVIEW
Control Board – Rear
There are three connectors on the Control Board.
When the G-System is assembled, the Control Link
connectors on the Control Board and on the GFX01 are
connected with a short Cat 5 cable.
When the GFX01 is mounted in a rack, a longer Cat 5
cable (not supplied) is used. Use a high quality Cat 5
cable with XLR housing for maximum stability.
Expression pedals can be connected to either the GFX01
(when the unit is assembled) or to the Control Board
when the GFX01 is mounted in a rack.
It is possible to connect two expression pedals to the
Control Board and at the same time connect two
expression pedals to the GFX01. This gives you two
“handles” for each of the parameters assigned to these
connectors, which you can place on stage where
required.
For more information on expression pedals, please refer
to the relevant sections of this manual.
GFX01 – Front
Control Link
Use a standard Cat 5 cable to connect the Control Board
to the GFX01. A short cable is already mounted upon
delivery when the G-System is assembled.
When you detach the GFX01 from the Control Board and
mount it in a rack, use a Cat 5 of suitable length (max.
15 meters).
18
We suggest using a “road-proof”, high quality Cat 5 cable
with XLR housing.
OVERVIEW
Mounting the G-System in a Pedal- Flightcase
Though the G-System is built from heavy-duty materials,
you may wish to mount it in a flightcase for extra
protection on the road.
Therefore, the G-System’s side panels have four screw
threads (Ø 4mm).
Be sure to use the correct type of screws (M4) to
avoid damaging the threads.
Instrument Input
The Instrument input on the front of the GFX01 is
identical to the Instrument input on the rear. This is very
convenient when the GFX01 is mounted in a rack and
you wish to connect your guitar to the front.
You cannot connect guitars to both of these inputs
at the same time. Which input to use is set up via
the Input Select parameter located in the Global
Levels menu. - See also page 35.
19
OVERVIEW
GFX01 – Rear

2
Input – Instrument
This is the input for your Guitar.
Note: If the G-System is separated and the
GFX01 is mounted in a rack, you may use the
identical Input on the front instead.
Loop 1 to 4
These loops are intended for connecting e.g.
drive/distortion pedals. Use regular unbalanced
jack/jack cables.
Connect a G-System’s “Loop Send” to the input
of the pedal and connect the output of the pedal
to the same loop’s Return connector.
All four loops are constantly sending. A loop only
breaks when the 1/4" Return jack is connected.
This allows you to split your lead signal, feeding
multiple destinations, so you can e.g. use a
Loop Send as a dry signal for a “3-way setup”.
3
Insert
This loop is intended for a pre-amp. If cables
longer than 3 feet are used, they should be
balanced, even if the connectors on the pre-amp
are unbalanced. When balanced cables are
used, a special pseudo balanced circuit will
20
reduce the noise which would occur when using
unbalanced cables.
4
Output
Left/Right output to your amp or amps.
5
Power Outputs
4 x 9 Volt DC to power connected pedals.
Maximum combined load on these outlets is
200mA. Please check the specifications on
connected pedals: Ring (+), Pin (-).
6
SW Out (Switch Out)
The two 1/4" stereo jack switch connectors can
be used to switch channels e.g. on a pre-amp or
a combo amp either at preset change or when
sending a CC change.
Switching options are:
– Tip to Ground
– Ring to Ground
– Tip and Ring to Ground
– No Connection
for each of the two connectors.
Depending on the channel switching facilities on
your pre-amp, different cables should be used.
OVERVIEW
Schematics for some amps are available at
www.tcelectronic.com. If you cannot find your
amp type there, please contact the manufacturer
of your amp.
7
Pedal In – Exp. (Expression)
Connector for an expression pedal to control e.g.
pitch in a whammy effect.
8
Pedal In – Vol (Volume)
Connector for an expression pedal.
A connected expression pedal will per default
control the Input Gain parameter.
9
MIDI IN
On the MIDI IN port, the G-System can receive
MIDI information such as MIDI Program Change
messages (for preset changes) and Continuous
Controllers (MIDI CCs). You can use these to
remote-control G-System parameters.
10
MIDI OUT
The G-System sends out MIDI Program Change
messages when a preset is recalled.
11
USB
Use the USB port to update the G-System’s
software from a computer.
12
S/PDIF – Digital Out
Digital output, e.g. for feeding a digital audio
recorder.
13
Power Input
The G-System’s switch mode power-supply
accepts from 100 to 240 Volts AC.
21
TYPICAL SETUPS
Pre-amp
The pre-amp generates your basic tone. It usually has 2
or more channels. E.g:

We are quite aware that not all amps are built and
labeled exactly alike and the generic explanations above
must therefore be considered as a basic guide. We also
recognize the importance and tone-differences of the poweramp models, tube-types etc. - This page is a reference for basic
understanding of the principles of guitar amplification only.

Effect
Power-amp
The power-amps main object is to amplify the sound
generated by the pre-amp and effects that are placed in
front.
Head
A “head” is a pre-amp and a power amp built into one
box. It is as simple as that.
The Input on the front is the pre-amp input.
The effect loop Send – is the pre-amps output.
The effects loop Return – is the Input of the power-amp.

If you an experienced gear “nerd” already, this page will not apply to you. This page gives information on a few
basic issues regarding amp types.
Generally said - all setups include both a pre-amp and a power-amp. This applies whether it is a Head, a Combo or a split
system with separate pre/power-amp. How to enter and exit these components is a different story. However, “Send” is
usually equal to “Pre-amp out” and “Return” is usually equal to “Power-amp in”.
TYPICAL SETUPS
In this section we will take a look at some examples of how the G-System can be connected to your gear. There
are probably no two setups that are 100% identical. We suggest you look for the setup that comes closest to your
own.

This setup is similar to the one described in the first
example, but we have now added a pre-amp to the Insert
loop. You can decide to have the pre-amp in or out of the
signal chain per preset, but you will probably prefer to
have it “on” at all times. This is configured in the Utility
menu, which you can access in Menu Mode.
With a pre-amp in the signal chain, you can chose to
connect the G-System to the input or the effects return
(“power-amp in”) on the combo amp.
Using the regular input on the combo amp gives you a
“double-pre-amp” setup where you can use the tone
controls on the combo to color your sound. This has
become a popular setup with amplifiers like the Vox AC
30, Fender Bassman etc., but using it introduces more
noise than using the effects loop return connector.

In this setup we are using a head as both pre-amp and
power amp. The pre-amp section of the head is
connected to the G-System’s Insert loop. Set the Insert
loop to “on” on all G-System presets, using the Utility
menu.
Look at the illustration and see if you can follow the
signal chain:
• Connect your guitar to the G-System’s Input.
• Up to four pedals can be connected in loops 1 to 4.
• Via the Insert loop’s “Send”, the signal is sent to the
head’s input.
• The head’s pre-amp out/send goes to the G-System’s
Insert loop “Return”. This way, the entire signal from
the drive pedals and the pre-amp section of the head
is returned to the input of the G-System’s effects
section.
• Via the G-System’s Out Connector, the signal is sent
to the head’s return – which is actually the input of
the head’s power-amp section.

In this particular setup, the center amp is receiving the
dry signal only – i.e, with no effects apart from those
added via the active pedals in Loops 1 to 4.
The left and right amplifiers receive only the effects.
On all G-System presets, “Mix” must be set to 100%.
In this particular setup, the mix of the effects is set solely

Important!
•
When the GFX01 is separated from the Control
Board, we strongly recommend mounting a 1
unit standard blank faceplate instead to ensure
maximum stability.
•
•
Unmount the GFX01 (the 19" unit) from underneath
the Control Board by unscrewing the four 6mm
screws.
Replace the short CAT 5 cable with a longer cable.
Mount the 19" GFX01 in your rack.
Please note that some racks require 5mm screws,
while others require 6mm screws. The G-System
is assembled using 6mm screws. Use appropriate
screws for your rack.
For advice on how to connect the drive and
expression pedals, please refer to the descriptions
on the previous pages.
28
If you do not use a Cat 5 plug with angled
XLR housing, you can turn the wings that
are holding the blank faceplate by 180
degrees to make space for a normal XLR
plug.
This is easily done:
• Unscrew the two screws in each side-panel.
• Turn the wings by 180 degrees.
• Mount the wings again using the screws.

Other Important Issues
Regarding Setups
The following is a list of other important issues you
should take care of when setting up your system. Please
refer to the relevant sections of this manual. Use the
Table of Contents (page 3) for directions.
Use correct cables for …
- Loops 1 to 4
(Quality mono jack/jack cables)
- the Insert loop
(Quality jack/jack cables – use balanced cables if
they are longer than 1 meter)
- Expression pedals
(Mono or stereo, - depending on the type of
expression pedal used).
Calibrate your expression pedals
Expression pedals must be calibrated for best
performance.
Use the Locking functions to protect settings
• Lock the Routing type if you only need to use one
routing.
• Lock the Insert loops if you have a pre-amp
connected in that loop and wish to use the pre-amp in
all presets.
• Lock the EQ section if you use the same EQ in all
presets (i.e., as a “master EQ”).
• Lock the Boost level to have the exact same boost
level in all presets.
• Lock Relays to keep same Relay positions on all
presets.
All Locking functions are located in the Utility menu.
whenever you just want a little extra power for certain
phrases and don’t want to create a new preset with a
different level.
Notice that the “Boost Max” parameter found in the
Levels menu limits the available amount of boost.
Get the most out of your amp(s)
using switch options
You can switch channels on your amp/pre-amp using the
four relays on the two stereo jack connectors on the GSystem.
To set up Relay switching, press EDIT, turn PAGE to
select RELAYS and press ENTER.
Read the section on Relays for detailed information.
Input Select parameter
The GFX01 has two Instrument inputs: one on the front
and one on the rear. You have to tell the G-System to
which connector you have connected your guitar.
This is set up using the Input Select parameter, which is
located in the Global Levels menu. The options are
“Front” and “Rear”.
Make good use of the Boost feature
You can set a boost level as part of each preset and
activate it using the BOOST switch. Per default, the
boost is set to +6dB on all factory presets, but you can
boost to as much as 10dB. You will enjoy this feature

PLAY MODE & EDIT MODE
Introduction
Play Mode is the mode you will use while playing. In Play
Mode you can recall presets, switch Effect Blocks on or
off and control parameters using expression pedals.
When you are in Play Mode, the top of the display reads
“PLAY”.
Example:
EDIT A
EDIT B
EDIT C
PLAY: 00-1
Funky White Chicken
What is a preset?
Use Presets to store and recall your favorite sounds by
pressing a single switch.
A preset holds the following information:
– Effect Blocks >>
(Reverb,
Delay etc.) – both active and
PRESET STORED <<
inactive ones.
– Settings for all Effect Blocks – for both active and
inactive ones.
– Status (active/inactive) for all loops.
– The assignment of the connected expression pedals.
– Various other parameters.
EDIT A
EDIT B
EDIT C
Factory Presets/User presets
Per default, the G-System holds 100 Factory presets. In
addition, you can store 200 presets in the User area.
Factory presets are organized in:
Banks A0 to A9 – with five presets each.
User presets are organized in:
Banks 0 to 39 – with five presets each.
Use the UP and DOWN switches to select Preset banks.
Use the PRESET switches 1 to 5 to recall the Presets in
the current bank.

Factory Presets
The factory presets show many combinations of effects
and you will probably find many of them to be excellent
starting points for your own presets.
In all factory presets, both the four effect loops and the
Insert loop are deactivated.
This means that although you may wish to use a factory
preset as a starting point, you will have to activate the
loops for each preset and store them in the user bank to
use the pedals and pre-amp connected to the loops.
After having worked with the G-System for a while, you
will therefore most likely find yourself working in the User
bank all of the time and only using the Factory bank as
an inspiration for new ideas and sounds.
User Presets
You can store up to 200 User presets with your own
choice of effects, active loops, amp channel switching
etc.
Example: Recalling a preset
• Use the UP/DOWN switches to select the desired
bank. The bank and preset number will blink,
indicating that the preset has not yet been recalled.
• Hit the PRESET switch (1 to 5) corresponding to the
preset you wish to recall.
The Bank and Preset number will now stop blinking,
indicating that the preset has been recalled.
The parameters found in the Utility menu are not stored
or recalled as part of presets.
It is possible to lock the settings of EQ, Insert loop and
Boost. To access the Locking functions, press EDIT,
press MENU and select Utility.
Locked parameters will not be recalled, either.

MENU MODE – PRESET ROUTING
Effect Routings:
What are they and what are they used for?
The available routings for Effects are:
Serial, Semi-parallel or Parallel.
Take a look at the illustrations below and read the
explanations to understand the differences.
Setting Routings
• Press EDIT and MENU and turn the PAGE encoder
to select the PRST* Routing menu.
• Press ENTER and select the desired routing by
turning Encoder C.
• Press ENTER to confirm the selected routing.
The selected routing can be stored as part of an
individual preset, or it can be locked for all presets by
setting Routing Lock to “On”.
*PRST - Preset
Serial Routing
The Serial routing connects all Effect Blocks “in a straight
line”, similar to a regular guitar stomp box setup. This
means that each Effect Blocks affects the following
effect(s).
If a delay with a long delay time is used in
combination with a reverb, you may find the
added Reverb on the Delay repeats disturbing. In
that case, use either the Semi Parallel or Parallel
routing.
35
MENU MODE – PRESET ROUTING
Semi Parallel Routing
The Semi Parallel routing connects most Effect Blocks
serially, but the Reverb and Delay blocks are now
connected in parallel. Consequently, the Delay and
Reverb effects do not affect each other. This means that
e.g. the repeats of the Delay are not reverberated.
Parallel Routing
In the Parallel routing, the same signal is fed to the input
of the Modulation, Pitch, Delay and Reverb sections, and
therefore these effects will not affect each other.
36
The parallel connection of the Reverb and Delay may
help to “clear the effects picture” when using both Delay
and Reverb.
MENU MODE – PRESET ROUTING & GLOBAL LEVELS
Left/Right Output levels
In the Preset Routing menu it is also possible to store
individual levels for Left and Right Outputs.
The range is -100 to 0dB.
These parameters allow you to e.g. use two different
amps for a dual mono setup and decide for each preset
which amp to send to. You can even send to both and at
levels of your own choice.
Routing Lock
For each preset, you can choose which of the three
routings you want to use. But if there are no specific
benefits gained from changing between routings (mostly
there aren’t), we suggest that you use the Routing Lock
function.
With the Routing Lock function activated, you will not
have to worry about selecting a routing for each preset.
In addition, you will benefit from the smoothest preset
changes possible.
Many guitarists choose the Serial routing and stick with it.
Setting Routing Lock
• Press EDIT, then MENU and turn the PAGE Encoder
to select the Utility menu.
• Press ENTER and select Routing Lock by turning the
PAGE encoder.
• Set to “On” or “Off”.
• Exit by pressing EDIT.
Optimizing the Noise Level
Here is some advice on how to reduce noise and how to
get the best signal-to-noise ratio with the G-System.
Cables
First of all: Good cables are essential! We advice that
you use properly shielded cables throughout your entire
system, but remember that the quality of the cable
connecting a guitar with passive pickups (e.g. a Strat
type) to the G-System input is a very sensitive point in
the signal chain. The few extra bucks for good cables are
well spent.
Avoid max. levels on connected Pedals and pre-amp.
The loops have a great dynamic range and will accept
most pedals on the market. However, it is possible to hit
the loop returns too “hot”. Max levels on pedals in loops
may cause internal overload in the G-System, resulting in
digital clipping. Therefore, you should work with
reasonable levels on the connected loops.
Not good
Good !
The Insert Loop
If you chose to have a pre-amp in the Insert loop and
place the pre-amp far away from the G-System* we
HIGHLY recommend using balanced cables. This also
applies if your pre-amp has no balanced connectors
(most haven’t).
When you use balanced cables to connect a pre-amp to
the Insert loop, a special pseudo-balanced circuit will
reduce the noise otherwise introduced.
* More than a meter
Input Level
The G-System’s Instrument input is per default adjusted
to match most guitar pick-up levels. However, you can
37
MENU MODE – GLOBAL LEVELS
fine-tune the Input sensitivity to achieve best
performance and best signal-to-noise ratio.
•
•
Press EDIT and use the INPUT Encoder (first
Encoder in the top row).
Also set the Boost Max. and Loop Headroom
parameters.
All level parameters in this menu are global and not
stored as a part of presets.
To Access the Global (Gbl) Levels Menu:
• Press EDIT and then MENU.
• Select Gbl Levels using the PAGE Encoder.
• Press ENTER.
EDIT A
EDIT B
Volume
Range: -100 to 0dB
The volume parameter can control the level either before
or after the effects section. This is set up using the
Volume Position parameter (see below).
Volume Position
The Volume Position parameter defines where the
volume is controlled. The options are:
0dB
Input Gain
Range: -8 to 18dB
This parameter sets the input gain of the instrument input
where you plug in your guitar.
When you have set the Input gain correctly, the red LED
on the Input meters occasionally lights up when you hit
the guitar hard with a “big” chord on a clean sound.
To quickly change the Input
gain, hit “EDIT” and turn the
Input Gain encoder (switch #1).
Hit “EDIT” again to exit back to
Play Mode.
Loop Level
Range: 0 to 10dB
This parameter sets how hard you hit the input of the
loop section. If you feel that the drive pedals in the loops
give more overdrive than when not connected in the
G-System, you can use this parameter to compensate.
Loop Headroom
This parameter controls the sensitivity on the input side
of the effects section. If the pedals and pre-amp connected

Levels on Devices in Loops
Max gain on one or more active pedals may cause
internal overload in the G-System. Internal

EDIT C
LEVELS MENU
Input Gain
to the loops boost the signal considerably, you can either
reduce the output level of these devices, adjust the Loop
Headroom parameter – or both. The range of this
parameter depends on the Loop level setting.
Input: The volume is controlled right after the loops and
before the effects. This allows for effects such as Delay
and Reverb to “hang”, even if you lower the level using
an expression pedal.
Output: The volume is controlled after the effects. This
means that the volume of the entire signal, including
effects, is controlled.
Output Level
This parameter sets the overall Output level of the entire
G-System. This is where you trim the G-System to your
amp’s input. You will have to rely on your ears for this
setting, as most amps do not have an input meter.
Driving the input of your amp hard may result in overdriving
the amp’s input. If this is the sound you are looking for –
go for it! If not, lower the Output level of the G-System.
To quickly change the Output level, hit EDIT and
turn the Output Level Encoder (Switch #6). Hit
EDIT again to return to Play Mode.
BOOST FUNCTION
Boost Max.
Range: 0 to 10dB
A boost in the digital world is only possible if you do not
already operate at maximum level. A boost therefore
derives from releasing an attenuation. This parameter
sets the general attenuation of the signal, thereby limiting
the amount of boost you can set using the Boost menu.
Many guitarists feel that 6dB boost is more than enough
for solos etc. If you feel the same, set the Boost Max
parameter to 6dB. You might be tempted to set Boost max
to 10dB all the time. Don’t, as it will worsen your signal to
noise ratio (in this example, by 4dB).
Setting up the Boost Level of a Preset
• Press EDIT, then BOOST and set the level using
Encoder C.
• Store the preset.
Input Select
Range: Front or Rear.
A guitar can be connected to either the front or the rear of
the GFX01. Typically the Front connection is used when
GFX01 in mounted in a rack and the Rear connection
when G-System is used in its base configuration,
assembled on the floor. Front and Rear connections
cannot both be open at the same time.
Boost
So you have made a good set of presets and all your
levels are well matched … But wouldn’t it be nice if you
could just hit a single switch and boost any of your
sounds to a “solo” level. With the G-System, you can!
The BOOST switch:
• The boost level (in other words: how much you boost)
can be set individually for each preset.
• The maximum boost is 10dB.
If the Boost Lock parameter found in the Utility menu
is set to “on”, you have a default boost level applied
to all presets.
When activating the Boost Lock function in the Utility
menu, it is the boost setting of the currently recalled
preset that will be applies to all presets.
39
MENU MODE – PEDALS
Expression Pedals:
What Are They For?
Expression pedals are used to manually control certain
parameters such as volume. Instead of having your
entire signal go through 10 meters of cable or more
using a regular volume pedal, you can connect an
expression pedal and use it to adjust the G-System’s
volume parameter.
But expression pedals can do much more. How about
letting an expression pedal control the pitch as a
Whammy pedal, or the level of Delay repeats, or the
speed of a Tremolo? There are countless possibilities.
For each preset, you can define which parameters the
expression pedals should control. This means that in
each preset, the pedals can serve different functions.
You may, however, prefer a setup where e.g. the
expression pedal controlling the volume always controls
the volume. That is why you can set the pedal
assignment as a global parameter.
If we look at the G-System with the Control Board and
GFX01 separated, you will see that there are two
Expression Pedal Inputs on the GFX01:
For example, you can place two pedals onstage right
next to the Control Board and another two on the
“catwalk” for full control when you solo.
All four Expression Pedal Inputs can be
individually calibrated.
The Vol Pedal Input is per default assigned to the GSystems’ In Gain parameter and connecting an
expression pedal to that connector will automatically
allow this pedal to control that parameter.
However, as previously described it is entirely up to you
what to control with the expression pedals.
Important Note
•
•
True expression pedals can be used to control
all types of parameters in G-System.
Regular volume pedals should only be used to
control volume parameters. Using a regular
volume pedal to control e.g. whammy or wah
effects, will most likely give an unsatisfying
result.
Connecting Pedals
Depending on the type of expression pedal used, the
pedal should be connected using either a regular mono
1/4" jack-to-jack cable or a stereo 1/4" jack-to-jack cable.
… and two Expression Pedal Inputs on the Control
Board:
Mono
Stereo
These connectors are “clones” – meaning that you can
control two different parameters per preset, but you can
actually hook up two expression pedals for each function.
40
If you are not sure, you may have to try both types.
The G-System measures the signal on your expression
pedals output connector. Therefore only one cable
should be used per expression pedal.

Momentary: Use this setting if you have connected a
pedal with a momentary switch – in other words, a
switch type that is only active as long as it is pressed,
such as a keyboard hold pedal.
Alternating: Use this setting if you have connected a

switch type is a switch that stays in one position once
it is pressed and needs to be pressed once more to
return to its previous state.
Exp or Vol: Select whether it is a volume or an
expression pedal you have connected.
As explained on page 40, regular volume pedals
should only be used to control volume parameters.
Expression pedals work well with all types of
parameters.
Vol Master & Exp. Master
When a preset change occurs, the value of a parameter
can be controlled either by the expression pedal or the
preset. This parameter determines which of the two
applies.
There are two options for parameters assigned to pedals:
Preset: The parameter value stored as part of the preset
rules – regardless of the current position of the
expression pedal controlling the parameter.
Global: The position of the expression pedal is identified
at the moment of preset change, and the value stored as
part of the preset is overwritten by the pedal.
Example:
Let us say you are using your pedal to control Delay mix
42
in preset #1. In preset #2, you want to use the pedal to
control the Whammy Pitch parameter. Preset # 2 is set up
with the Pitch parameter set to 0%. Because you just used
your pedal for Delay mix in preset #1, you leave it at 15%.
The big question is: When you change to preset #2, do
you want the Pitch parameter to stay at 0% – as it is
programmed in the preset –, or do you want the pitch to
“grab” the 15% position of the pedal?
By setting the Exp. Master parameter to “Global”, the
current pedal position affects the controlled parameter
immediately after the preset change.
By setting the Exp. Master or Vol. Master parameter to
“Preset", the preset value rules at preset change.
The expression pedal will take control of the parameter
only once you touch the pedal after preset change.
Do you want your volume pedal to be global, i.e.
not affected by preset changes?
Set the Vol. Master parameter to “Global” and
you are in business.
Calibrating Expression Pedals

Using Expression Pedals to
Control Specific Parameters
Once the connected Expression/Volume pedals are
properly set up and calibrated as explained in the
previous section, it is time to define which parameters
they should control.
Basics
• Press EDIT to enter Edit Mode.
• Press ENTER two times. You can now access the
complete list of parameters in the current preset that
can be controlled via the connected pedals and
Encoders A, B and C.
The display now looks similar to this:

EDIT C
None-> Pitch Voice1
•
Enc A, Enc B and Enc C: Refers to Encoders A, B
and C when in Edit Mode.
Just like expression pedals connected to Vol or Exp,
the three Encoders A, B and C can also be assigned
and used to control pre-selected parameters.
•
Min, Mid and Max: Sets the value corresponding to
the Mid, Mid and Max position of the expression
pedal.
Example
Imagine that you have assigned Encoder A to control
Delay Feedback. This means that at the end of the solo
or song, you can perform that über-cool trick of
increasing the feedback to 100% for that special vintage,
non-stop-repeats “on-your-knees” effect.
Setting Up Enc A, B and C
Follow the exact same procedure as explained above in

Utility
Tap Master
Range: Preset or Global
Determines whether at preset change tempo related
parameters follow the values set in presets or the
globally tapped tempo.
Example:
You have tapped a tempo of 500ms as a global tempo.
The preset you are about to change to has a – tempo
dependent – delay time of 350ms. When the Tap Master
parameter is set to Preset, the G-System will set the
delay time to 350ms (as it is stored in the preset).
When the Tap Master parameter is set to “Global”, the GSystem will ignore the 350ms value set in the preset and
use the (global) 500ms value instead.
Insert Lock (loop 5)
Range: On/Off
This parameter locks the state of the Insert loop to its
current state. This feature is typically used when you
want a pre-amp connected in the Insert loop to be “on” at
all times.
When you activate the Lock feature, the On/Off status for
the currently recalled preset will be used on all presets.
Boost Lock
This parameter locks the settings of the Boost section.
When you activate the Lock feature, the Boost settings
for the currently recalled preset will be used on all
presets.
EQ Lock
This parameter locks the settings of the EQ section.
When you activate the Lock feature, the EQ settings for
the currently recalled preset will be used on all presets.
Relay Lock
Range: On/Off
With Relay Lock set to “On” the relays are locked at their
current positions. This means that they will not be altered
at preset changes. You can, however, assign a switch to
alternate between Relay positions A and B if you like.

channel but otherwise keep the same effects.
Setting up
• Connect a stereo-to-stereo 1/4" jack cable from SW
OUT1 or SW OUT2 on the back of the GFX01 to the
channel switch connector on your amp.
• Recall the preset you wish to combine with your
amp’s clean channel.
• Scroll through the Rel.A combinations until your
amp’s clean channel is selected.
Set the Relay parameter to A and store the preset.

What Can the “B” Option Be Used For?
Each preset can store two Relay configurations. You can
assign a switch to toggle between these configurations
(Toggle) or to temporarily activate the second
configuration (Hold).
As a result, the G-System can select the amp channel of
your choice at preset change. Then, within that preset,
you can use a switch assigned to “Relay” to alternate
between Relay A and Relay B settings.
Example
Let us assume the following:
• You have a regular combo-amp with a clean channel
and a lead channel.
• The connector for the channel switching on the amp
is a regular stereo jack connector.
• You wish to make two presets: one with the clean
channel selected and one with the drive channel
selected.

Display
The G-System’s Tuner has two different indication
modes. These comprise the indication at the bottom of
the big red Tuner and the preset number display.
Bar
A bar appears at the bottom of the tuner display. When
the bar is visible, the note played is not in tune. The
longer the bar, the more out of tune the note.
Strobe
In Strobe Mode, a pattern of two dots will move either
towards the left or towards the right, depending on
whether the played note is too high or too low. Tune the

EFFECTS – FILTER
This section of the manual describes the G-System’s
effects and their parameters. To learn how to
navigate the G-System’s menus, please refer to the
preceding chapters.
Resonance Filter
The G-System’s Resonance filter is basically a hi-cut
filter with adjustable Q-factor (Resonance).
With increased Resonance value, the filter peak at the
cutoff frequency gets very narrow and steep. This
phenomenon is the very core of the characteristic sound
of resonance filters.
Style
Range: 2nd or 4th
The Style parameter changes the steepness of the filters.
2nd order filters are 12dB/Octave while 4th order filters
are 24dB/Octave. 4th order filters will “ring” or resonate
more than 2nd order filters.
Hi-Cut
Range: 160Hz to 14kHz
Determines the frequency above which the hi-cut filter
will attenuate the high-end frequencies of the generated
effect.
Resnce – Resonance
Range: 0 to 100%
Sets the amount of resonance on the hi-cut filter.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
52
Touch Res Filter –
Additional Parameters
The Touch Resonance filter creates an effect similar to a
Touch Wah. The sweep through a frequency range is
controlled via the Input’s dynamics.
Sense – Sensitivity
Range: 0 to 10
The sensitivity should be set according to the Input level
on the Filter block. The lower a setting, the harder the
effect section should be hit to create the “whack” effect.
Response
Range: Slow or Fast
This parameter sets the response time, i.e. how fast the
“quack” should occur when you hit the strings.
Fmax – Frequency Max
Range: 1kHz to 10kHz
This parameter can limit range of the sweep. Most likely
you will find a full range being too harsh and high-end.
You will probably find settings between 2kHz and 4kHz to
prove excellent.
EFFECTS – FILTER
Auto Resonance Filter –
Additional Parameters
Speed
Range: 0.050Hz to 20Hz
This parameter sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
Shape
Range: Triangle or Sine
Defines the type of curve used. The Triangle shape has
a sharp peak point, while the Sine type gives a smoother
shift.
Fmax – Frequency Max
Range: 1kHz to 10kHz
This parameter can limit the range of the sweep. Most
likely you will find a full range being too harsh and highend.
You will probably find settings between 2kHz and 4kHz to
prove excellent.
Wah Wah
With this effect type, you can create the same effect as
with a dedicated wah pedal, which you can control
manually. All you need to do is assign an expression
pedal to control the Sweep parameter.
When you select a Factory preset using this Wah Wah
effect, an expression pedal connected to the Exp.
connector is automatically assigned to control this
parameter.
Sweep (Freq)
Range: 0 to 100%
With an expression pedal set up to control this
parameter, you have created a wah pedal.
Range (Instr Mode)
Range: Low or high
This parameter sets which frequency areas should
primarily be emphasized.
AutoOn
Range: Off, 0.3s, 0.5s, 1s, 3s, 5s, 10s or Inf
When set to “off” the Wah effect is switched on/off using
the FILTER switch just like any other regular effect.
With any other setting the Wah effect is automatically
switched on when the expression pedal controlling the
Sweep parameter is moved.
Once the pedal is left in a fixed position the Wah effect is
turned off after the period of time set by this parameter.
“0.3” seconds is almost instantly - “Inf” means never.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
53
EFFECTS – FILTER
Touch Wah
Auto Wah
The wah effect occurs when a relatively narrow
frequency area is boosted and swept through a
frequency range. The sweep is controlled by the input
dynamics. This means: the harder you hit the strings, the
higher the boosted frequency will be.
The wah effect occurs when a relatively narrow
frequency area is boosted and swept through a
frequency range.
The sweep is controlled by a low frequency oscillator
(LFO).
Sense – Sensitivity
Range: 0 to 10
Adjust the sensitivity according to the level present on
the input. Be aware that changing any level parameter on
devices prior to the Touch Wah effect will require a
different sensitivity setting to get the same Touch Wah
“feel”.
Speed
Range: 0.050Hz to 20Hz
This parameter sets the speed of the effect.
Resp – Response
Range: Slow or Fast
This parameter determines the speed of the sweep.
Range (Instr Mode)
Range: Low or High
This parameter determines whether the Touch Wah is
particularly sensitive to high or low input frequencies.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 2 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
Shape
Range: Triangle or Sine
Sets the shape of the frequency boost.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
Range (Instr Mode)
Range: Low or High
Determines whether the Auto Wah is particularly
sensitive to low or high input frequencies.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the

EFFECTS – FILTER
Formant Filters – Introduction
The Formant filters are somewhat special. The
characteristic vowels of the human speech can also be
described as formants. Imagine a pedal that does not
say “WAH WAH”, but instead goes “OOWEEAAOOWEEAA”.
If you set up an expression pedal to control the sweep
parameter, you can use the pedal to sweep through the
vowel sounds.
Formant parameters – Generic
Touch Formant –
Additional Parameters
The Touch Formant effect is controlled by the input
dynamics – similar to a Touch Wah.
Sensitivity
Range: 0 to 10
The Sensitivity parameter must be set according to the
base level of your particular preset.
Low, Mid & High
Range: Heat, Hit, Head, Had, But, Father, All, Boot, Foot
or Bird.
We have used names phonetically similar to the types of
sounds emulated by that particular formant filter.
Response
Range: Slow or Fast
This parameter determines the speed of the sweep when
you hit the strings.
Sweep
Range: 0 to 100%
Assign an expression pedal to control the Sweep
parameter, and you have full “live” control of the
emulated vowels.
Auto Formant –
Additional Parameters
Bright
Range: 0 to 100%
Depending on the Low, Mid and High settings, you may
need to adjust the high-end frequencies of this effect.
Resonance
Range: 0 to 100%
Use this parameter to increase filter emphasis. Use it
with caution, as high settings combined with certain
vowels may sound very harsh.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
Speed
Range: 0.050 to 20Hz
This parameter sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
LFO Shape
Range: Triangle or Sine
This parameter sets the shape of the frequency boost.
Bright
Range: 0 to 100%
Depending on the Low, Mid and high settings you may
need to adjust the high-end frequencies of this effect.
55
EFFECTS – COMPRESSOR
Compressor
Advanced Type
Introduction
A Compressor is used to control the dynamic content of
a signal. It can be used both for levelling out the signal’s
dynamics (thereby letting your guitar sound stand out
clearer) and also for more radical, very recognizable
effects. The G-System provides three basic types of
compression. They assist you in finding the most
appropriate sound for your particular application.
This type offers full control over all compression
parameters.
Advanced Mode
This mode gives you access to all the common
compressor parameters. This means you have full
control over the compressor.
Ratio
Range: Off, 12:1 to Infinite:1
This parameter determines how hard the signal is
compressed. (see illustration above).
Sustaining Mode & Percussive Mode
In these modes, we offer fewer but very effective
“handles”. While the Sustaining Mode is used to achieve
rather extreme compression effects, the Percussive
Mode is more suitable for limiting purposes.
Example: With a Ratio setting of 2:1, an Input signal with
4dB above Threshold is reduced to only 2dB on the
Output. The Infinite setting gives you a Limiter function.
Illustration – Basic Compression
Threshold
Range: -40dB to 0dB
When the signal exceeds the set Threshold point, the
Compressor is activated. The signal’s level above this
Threshold point is processed according to the settings of
the Ratio, Attack and Release parameters (see below).
Attack
Range: 1ms to 140ms
The Attack time is the response time of the Compressor.
The shorter the Attack time, the sooner the Compressor
will reach the specified Ratio after the signal rises above
the Threshold point.
Release
Range: 50 to 2000ms
The Release time is the time it takes for the Compressor
to release the gain reduction of the signal after the Input
signal drops below the Threshold point again.
As this illustration shows, the output signal is attenuated
in accordance to the set ratio when the input signal
exceeds the Threshold point. The Attack parameter
specifies how fast the attenuation is achieved. Use the
Gain parameter to compensate the overall loss of level
that might result from compression.
56
Gain
Range: -12 to +12dB
Use the Gain parameter to compensate for the level
changes caused by the applied compression.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
EFFECTS – COMPRESSOR
Sustaining and Percussive Types
The Sustaining and Percussive Types hold fewer handles
than the Standard mode. Individually tuned these types
allow you two easily setup commonly used compression
styles.
Use the Sustaining type to achieve the subtle
compression settings that will give you plenty of sustain
without “smashing” the sound too hard.
Use the Percussive type to obtain the hard, obvious and
easy recognizable compression often achieved with
classic stomp box compressors
Though tuned differently the two types hold common
parameters.
Drive
Range: 1 to 20
A combination of Threshold and Ratio parameters that
sets the compression amount. Though auto make-up
gain is applied you may need to adjust the level slightly
using the Gain parameter when extreme settings are
used.
Response
Range: 1 to 10
Sets the time it takes for the Compressor to release the
compression. The lower setting the more you will hear
the compression.
Gain
Range: -12 to +12dB
Depending on the settings of Drive and Response
parameters you may need to adjust the Gain.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.

EFFECTS – MOD
Chorus
Introduction
The G-System offers two types of Chorus: the simple
Classic Chorus and the Advanced type that includes a
couple of extra parameters.
The basic idea of a chorus effect is to split the signal and
pitch modulate one of the signals slightly, then mix the
two signals again.
Classic Chorus
Speed
Range: 0.050Hz to 20Hz
This parameter sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or the
tempo set by the Speed parameter in each preset
should be used at preset change.
Depth
Range: 0 to 100%
The Depth parameter specifies the intensity of the effect.
The value represents the amplitude of the modulating
waveform.
Hi-Cut
Range: 20Hz to 20kHz
This parameter reduces the high-end frequencies in the
Chorus effect. Try using this parameter if you feel the
Chorus effect is too dominant in your sound and turning
down the Mix or Out level doesn’t give you the
dampening of the Chorus effect you are looking for.
58
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
EFFECTS – MOD
Advanced Chorus
Flanger – Introduction
Additional parameters to the Classic Chorus:
The Flanger belongs to the same “family” of modulation
effects as the Chorus effect. The signal is split, and one
of the signals is pitch modulated.
The characteristic “flanging” sound occurs when part of
the signal is slightly delayed and fed back to the input
of the effect algorithm. Experiment with the Feedback
parameter to get a feeling for the achievable effects.
Cho Dl – Chorus Delay
Range: 0 to 50ms
As described earlier, a Chorus/Flanger is basically a
Delay being modulated by an LFO. This parameter
allows you to change the length of that Delay.
A typical Chorus uses Delays at approximately 10ms,
while a Flanger uses Delays at around 5ms.
Though this not how a Chorus is normally used,
you may enjoy the “slap-back” resulting from
longer Delay times such as 30 to 50ms.
Ratio – Golden Ratio
Range: Off/On
TC research has shown that when the speed of a
modulation effect is increased, its depth should be
decreased accordingly to achieve the same amount of
perceived modulation. When the Golden Ratio parameter
is set to On, this value is automatically calculated.
Golden Ratio is a feature inherited from the classic TC
2290 processor.
Phase Reverse
Range: Off/On
Setting this parameter to On reverses the phase of the
processed signal in the right channel. This gives a very
wide Flange effects and a less defined sound.
Classic Flanger
Speed
Range: 0.050Hz to 20Hz
This parameter sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the
Speed parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or
the tempo set by the Speed parameter in each
preset should be used at preset change.
Depth
Range: 0 to 100%
The Depth parameter specifies the intensity of the
effect. The value represents the amplitude of the
modulating waveform.
Hi-Cut
Range: 20Hz to 20kHz
This parameter reduces the high-end frequencies in the
Flanger effect. Try using this parameter if you feel the
Flanger effect is too dominant in your sound and
turning down the Mix or Out level doesn’t give you the
dampening of the Flanger effect you are looking for.
59
EFFECTS – MOD
FeedB – FeedBack
Range: -100 to 100
This parameter controls the amount of feedback
(Resonance) of the short modulated delay that causes
the Flanging effect. When the Feedback is set too high
(above approximately 90% to 95%), this might introduce
internal feedback, resulting in a squealing noise that in
most cases is unwanted in flanging effects. Be aware of
this side-effect when experimenting at high volumes.
Negative values inverse the phase of the signal that is
fed back to the algorithm’s Input.
FB Cut – Feedback hi-cut
Range: 20Hz to 20kHz
A parameter that can attenuate the high-end frequencies
of the resonance created with the Feedback parameter.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
60
Advanced Flanger
Additional parameters to the Classic Flanger:
Fla Dl – Flanger Delay
Range: 0 to 50ms
Typically, Delay values around 5ms are used for Flanging
effects, whereas Chorus effects occur with Delay times
around 10ms. You are free, however, to choose Delay
times from 0 to 50ms.
PhaRev – Phase Reverse
Range: Off/On
Setting this parameter to On reverses the phase of the
processed signal in the right channel. This gives a very
wide Flange effects and a less defined sound.
Ratio – Golden Ratio
Range: Off/On
TC research has shown that when the speed of a
modulation effect is increased, its depth should be
decreased accordingly to achieve the same amount of
perceived modulation. When the Golden Ratio parameter
is set to On, this value is automatically calculated.
Golden Ratio is a feature inherited from the classic TC
2290 processor.
EFFECTS – MOD
Vibrato
The Vibrato effect modulates the pitch of the incoming
signal. The result is similar to the vibrato technique used
by vocalists. In contrast to a Chorus or Flanger effect, no
direct signal is combined with the pitch-modulated signal.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
Speed
Range: 0.050Hz to 20Hz
Sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or the
tempo set by the Speed parameter in each preset
should be used at preset change.
Depth
Range: 0 to 100%
The Depth parameter specifies the intensity of the effect.
The value represents the amplitude of the modulating
waveform.
Hi-Cut
Range: 20Hz to 20kHz
This parameter reduces the high-end frequencies in the
Vibrato effect. Try using this parameter if you feel the
effect is too dominant.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
61
EFFECTS – MOD
Vintage Phaser & Smooth Phaser
Introduction
The G-System provides two very effective phaser types.
The Vintage Phaser will give you a phasing effect similar
to the one found in old stomp boxes. The Smooth Phaser
is more subtle and less dominant.
The Vintage Phaser utilizes four all-pass filters. These
filters create a comb-looking effect on the sound
spectrum. When the filtered sound is mixed with the
direct sound, a “phasing” effect occurs.
The Smooth Phaser utilizes twelve all-pass filters. Due to
the higher number of filters, the Smooth Phaser simply
sounds smoother than the Vintage type.
Parameters and value ranges for the two Phaser types
are identical. The difference is the filter at the core of the
two Phaser models.
Speed
Range: 0.050Hz to 20Hz
Sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 2 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or the
tempo set by the Speed parameter in each preset
should be used at preset change.
Depth
Range: 0 to 100%
The Depth parameter specifies the intensity of the effect.
The value represents the amplitude of the modulating
waveform.
62
Fb – FeedBack
Range: -100 to +100%
This parameter controls the amount of feedback in the
Phaser. Negative values inverse the phase of the signal
that is fed back to the algorithm’s Input.
Range
Range: Low to High
Determines whether the phasing effect should be mainly
on the high or low-end frequencies.
Rev – Reverse
Range: On/off
Reversing the phase in one of the channels creates a
much wider sounding phasing effect.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
EFFECTS – MOD
Tremolo
Introduction
A Tremolo is basically a change of the signal level
controlled by an LFO. The G-System offers variations of
this effect; ranging from soft and smooth to hard and
aggressive.
Speed
Range: 0.050Hz to 20Hz
This parameter sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or the
tempo set by the Speed parameter in each preset
should be used at preset change.
Depth
Range: 0 to 100%
This parameter sets the intensity of the effect. A 100%
setting means that the signal is completely muted
between signal peaks.
Type
Range: Soft or Hard (Sinus or Square)
Two waveforms are available as modulation sources for
the Tremolo effect. Setting this parameter to Hard results
in a steeper effect. Listen and choose the appropriate
option.
Sine
Square
Width
Range: 0 to 100%
If you set this parameter e.g. to 20% with a Type setting
of Hard, the waveform will be on for 80% of one period.
With a Type setting of Soft, a 50% setting would yield a
full sine wave, whilst 0% and 100% would yield a crestto-peak and peak-to crest curve, respectively.
Pulsewidth
Hi-Cut
Range: 20Hz to 20kHz
This parameter attenuates the high frequencies of the
Tremolo effect. Use the hi-cut filter to create a less
dominant Tremolo effect without changing the effect’s
Depth.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
63
EFFECTS – MOD
Panner
Introduction
The Panner simply pans the signal between the left and
the right channel. Use this for extreme stereo perspective
effects.
Speed
Range: 0.050Hz to 20Hz
Sets the speed of the effect.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or the
tempo set by the Speed parameter in each preset
should be used at preset change.
Depth
Range: 0 to 100%
When you set this parameter to 100%, the signal will
sweep fully from the left to right. You will find, however,
that for most applications, a more subtle setting is more
appropriate, as it blends more elegantly with the overall
sound.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
64
EFFECTS – PITCH
Pitch Shifter
The G-System’s Pitch Shifter gives you two voices, each
with a fixed pitch distance to the Input note. The
maximum range for this effect is +/- one octave. The
signal processing within the G-System happens so fast
that you will never notice any “searching” for notes as
with many older octaver units or octaver stomp boxes.
You might try lowering one voice to -1200 cents (100
Cent equal one semitone). At a Mix level of 100 (full
effect, no dry signal), you will be able to get at pretty
good bass simulation.
Voice 1
Range: -1200 to 1200 Cent
This parameter specifies the pitch of the first voice. As
100 Cent equal 1 semitone, you can select any interval
between one octave below the Input pitch to one octave
above it.
Voice 2
Range: -1200 to 1200 Cent
This parameter specifies the pitch of the second voice.
As 100 Cent equal 1 semitone, you can select any
interval between one octave below the Input pitch to one
octave above it.
FB1
Range: 0 to 100%
This parameter determines how often the first voice will
be repeated by the Delay.
FB2
Range: 0 to 100%
This parameter determines how often the second voice
will be repeated by the Delay.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
Pan 1
Range: -50 to 50
This parameter sets the stereo position of the first voice.
Pan 2
Range: -50 to 50
This parameter sets the stereo position of the second
voice.
Delay 1
Range: 0 to 350ms
This parameter sets the Delay time for the first voice.
Delay 2
Range: 0 to 350ms
This parameter sets the Delay time for the second voice.
65
EFFECTS – PITCH
Octaver
Whammy
The Octaver gives you an additional voice with a fixed
pitch distance of either one or two octaves above or
below the Input note.
The Whammy effect allows you to control the pitch of an
added voice with an external Expression pedal.
For Factory presets including the Whammy effect, the
Expression pedal connected to the Expression Pedal
Input automatically controls the Pitch parameter, i.e. it
acts as a Whammy Pedal.
Dir - Direction
Range: Up or Down
This parameter sets whether the added voice should be
above or below the input note.
Range
Range: 1 or 2 octaves
This parameter sets the interval of the added voice. Use
the Direct parameter to determine whether the added
voice should be above or below the Input signal.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
OutLev – Outlevel
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
Pitch
Range: 0 to 100%
This parameter sets the amount of pitch shift relative to
the Range setting. A connected pedal adjusts this
parameter.
Dir – Direction
Range: Up – Down
This parameter determines whether the attached
Expression pedal should increase or decrease pitch
when moved in either direction.
Per default, pitch is up when the pedal is at “toe down
position”, i.e. this is the “Up” position.
Range
Range: 1-Oct/2-Oct
This parameter sets the range of the pitching effect.
Select 2-Oct for an extreme and 1-Oct for the more
commonly used, subtle Whammy effect.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
66
EFFECTS – PITCH
Detune
The Detune effect is – to some extent – similar to a
Chorus: The source signal is split and a specified amount
of the signal is detuned by an adjustable amount of
Cents (100 Cent = 1 semitone). The main difference
between the Detune effect and the Chorus effect is that
the Detune amount does not change: the modulating
pitch is specified as an offset to the original pitch.
The Detune effect comprises two voices. If you think your
sound is simply too direct and clean, try a setting with
only a few Cent off on both voices – e.g. +2 Cent on
Voice 1 and -3 Cent on Voice 2.
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
Voice1
Range: -100 to 100
This parameter determines the pitch offset for the first
Voice in the Detune block.
Voice2
Range: -100 to 100
This parameter determines the pitch offset for the second
Voice in the Detune block.
Delay1
Range: 0 to 350ms
This parameter specifies the Delay for the first Voice.
Delay2
Range: 0 to 350ms
This parameter specifies the Delay for the second Voice.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
67
EFFECTS - PITCH
Intelligent Pitch Shifter
The G-System Intelligent pitch-shifter is a 2 voice pitchshifter that allows you to play harmonies within a variety
of scales in any key. The range of the voices range from
minus 13 scale-steps below to 13 scales steps above
which equals +/- one octave plus a diatonic sixth.
Key
To allow the intelligent pitch-shifter to generate the
correct voices it is necessary to enter which key you are
playing in. Keys are listed as: C, C#, D , D#, E, F, F#, G,
G#, A, A#, and B.
Scale
WIth the scale parameter you set the type of scale you
intend to play. G-System covers the following scalestypes:

Voice 1-2
Range: -13 to Unison to 13
The intelligent pitch-shifter can add two voices within the
selected scale. The pitch-shifter automatically calculates
the correct interval according to the played note, selected
scale type and key.
Level 1-2
Range: -100 to 0dB
Sets the individual levels of the two voices.
Pan Position 1-2
Range: -/+50
Controls the panning position of each of the two voices.
0 is center position. By panning the voices you can
achieve a very wide spread sound.
Delay 1-2
Delay range: 0-50ms
To a get at natural sounding result is it obvious to
simulate that no two guitarist would play notes precisely
at the same time. To simulate this you can delay the
harmony voices slightly. Just 10-20ms of delay will give
in a smooth and natural sounding result.
Mix
Range: 0 to 100%
Sets the overall mix between the dry and processed
signal.
OutLev – Out Level

EFFECTS – DELAY
Delay – Introduction
The G-System offers not only standard Delay types but
also a few new ones. We believe that the following types
should cover all your delay needs:
•
•
•
•
•
•
•
Single Delay
Tape Delay
Reverse
Lo-Fi
Ping Pong
Dynamic Delay
Dual Delay
All delays feature true “spillover” – meaning the repeats
of the delay can ring out when you change presets.
The tempo of the delay can be defined in relation to a
Global tempo, which can be tied to an incoming MIDI
clock.
Common Parameters – Delay
The following parameters are identical for all Delay
types. Parameters specific to certain delays are
described in the relevant sections.
Delay
Range: 0 to 1800ms
This parameter sets the time between the delay repeats.
This is also known as the “length” of the delay.
Tempo
Range: Ignore, 2 to 1/32T (T= Triplet & D= Dotted)
When set to any value between 1 and 1/32T, the GSystem’s Global Tempo is subdivided according to this
setting. When set to “Ignore”, the speed set by the Speed
parameter is used instead.
The Tap Master parameter – located in the Utility
menu – specifies whether the Global tempo or the
tempo set by the Speed parameter in each preset
should be used at preset change.
Fb – Feedback
Range: 0 to 120%
This parameter sets the amount of feedback from the
output of the effect back to its input. Use the Feedback
parameter to set how many repeats of the signal you
would like to have.
Please use high settings with extreme caution.
Due to the spillover feature of the G-System,
there is no way to immediately cut off the delay
when you get an internal feedback at settings above
100%. If you do get internal feedback, either switch to a
different Delay Type or to a different preset that uses the
Delay, two times in succession.
Fblcut – Feedback LoCut
Range: 20Hz to 20kHz
Use this parameter to attenuate the frequencies below a
given frequency.
As with the Feedback Hi-Cut parameter, the delays may
blend in more nicely with the overall sound if you “thin
out” the effect at the low end.
Fbhcut – Feedback Hi-Cut
Range: 20Hz to 20kHz
With digital technology, every delay can be a precise
reproduction of the Input signal. But especially with long
Delay times, this is not always desirable, as these
pristine delays may disturb the original signal and result
in a “washed-out” sound. To compensate for this, use the
hi-cut filter, thereby emulating analog or tape style delay
units.
The Feedback Hi-Cut parameter attenuates the
frequencies over the set frequency, resulting in a more
“analog” sound that in many cases that will blend in
better with the overall sound.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
69
EFFECTS – DELAY
OutLev – Out Level
Range: -100 to 0dB
This parameter sets the overall Output level of this effect.
All Common Parameters
Please refer to the section “Delay – Introduction” for a
description of this Delay’s parameters.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
The range of the Delay time for this delay type is 50ms
to 800ms.
Single Delay
The Single Delay effect is the most simple and basic
delay type in the G-System. It comprises a single delay
line with all the common parameters.
All Common Parameters
Please refer to the section “Delay – Introduction” for a
description of this Delay’s parameters.
Tape Delay
This delay simulates historical, tape-based delays,
including the clipping sound that occurs when the
Feedback parameter is yanked past the 100% point. Try
experimenting with a high Feedback level combined with
high and low cut filters.
In addition to the “common” parameters described in
the introduction of the delay section, this delay has
the following parameters:
Drive
Range: 0 to 24dB
Use this parameter to simulate the slight deterioration of
the delay repeats due to clipping, which – in addition to
the loss of high-end frequencies – used to be one of the
main characteristics of historical tape delays.
Reverse
The Reverse delay is a great effect when a more
mysterious, exotic delay style is required. Use the
Feedback Hi-Cut parameter to soften the delay.
70
Lo-Fi
The Lo-Fi Delay will make your delays stand out. Try
experimenting with the “Drive” parameter as well as the
Feedback LoCut and Hi-Cut parameters to tailor the LoFi sound to your exact needs.
In addition to the “common” parameters described in
the introduction of the delay section, this delay has
the following parameters:
Drive
Range: 0 to 24dB
The higher you set the Drive parameter, the more
distorted the repeats become. The “drive” simulated by
this effect has a very “analog” feel.
Ping Pong
The Ping Pong delay causes the delay to alternate
between the left and right channels, resulting a very nice
stereo feel. Use the Width parameter to determine how
“stereo” you want this effect to be.
In addition to the “common” parameters described in
the introduction of the delay section, this delay has
the following parameters:
Width
Range: 0 to 100%
The Width parameter determines how far the left and
right repetitions should spread from the center.
EFFECTS – DELAY
Dynamic Delay
The Dynamic Delay is a feature that was initially
introduced in the well-recognized TC 2290. It allows the
dynamics of the Input level to actively alter the Delay
Output level, which leaves the source signal clear and
undisturbed while you play. The Dynamic Delay
delicately complements your performance.
Use the Sense parameter to determine when the delays
should re-surface. Use the Offset parameter to widen the
stereo image.
In addition to the “common” parameters described in
the introduction of the delay section, this delay has
the following parameters:
Offset
Range: 0 to 200
This parameter offsets the Delay repeats in the right
channel only. For a “wide” stereo effect, the delay in the
two channels should not occur at exactly the same time.
For a “wide” effect, a few milliseconds should do the
trick. Using more than that will give you anything from a
generous slap-back effect on the repeats to more
extreme effects.
Rel – Release
Range: 20 to 1000ms
Determines how fast the attenuation of the delay repeats
is released.
Dual Delay
This true Dual Delay lets you set two independent delay
taps, each with its own Tempo parameter, High and Low
cut, as well as a “Pan” knob.
In addition to the “common” parameters described in
the introduction of the delay section, this delay has
the following parameters:
Pan1 & Pan2
Range: 50L to 50R
Sets the panning position of the delay repeats for delay
lines 1 and 2.
Sense – Sensitivity
Range: -50 to 0dB
The sensitivity parameter determines how soon the delay
repeats should become audible in relation to the Input
signal level. This parameter acts a threshold between
your guitar signal and the delay repeats.
Damp
Range: 0 to 100dB
As explained in the introduction, the Dynamic Delay
attenuates the delay repeats level based on the present
Input. The Damp parameter sets the amount of
attenuation.

EFFECTS – REVERB
Reverb Types
Common Reverb Parameters
The G-System features four different Reverb classics. All
types have the same editable parameters, but the
reverbs’ characteristics vary.
Decay
Range: 0.1 to 20 seconds
The Decay parameter determines the length of the
Reverb Diffuse Field. The length is defined as the time it
takes for the Diffuse Field to decay approximately by
60dB.
Spring
The Spring algorithm is designed to reproduce the sound
of old spring reverbs, such as the ones used in vintage
guitar amps.
Hall
The Hall algorithm simulates a rather large hall and
preserves the natural characteristics of the source
material. Excellent when you strive for a discrete Reverb
with medium to long Decay times.
Room
The Living Room type simulates a relatively small, well
furnished room. In such a room, many reflections are
absorbed by soft materials, and the source signal is
reflected and sustained mainly from the walls.
Plate
Before the digital era, either reverberating springs or
large metallic plates were used to create reverb effects.
Plate reverbs sound diffuse and bright. They can be used
to make the processed signal “stand out”, rather than
blend naturally.
These brief introductions should only give you a hint in
terms of choosing the right one for a given application.
Take some time to listen to the different types,
experiment and don’t be afraid to be innovative!
PreDly – Pre Delay
Range: 0 to 100ms
This parameter defines a short Delay placed between the
direct signal and the Reverb Diffuse field. Use Pre Delay
to keep the source material clear and undisturbed from
the more diffuse Reverb Diffuse Field arriving shortly
after.
Shape
Range: Round, Square or Curved
The shape of the simulated room is of great importance
to the reverb characteristics. Try the various shapes.
Size
Range: Small, Medium or Large
Though the Decay time can be altered from 0.1 to 20
seconds on all reverb types, selecting a predefined
(room) size may get you closer to the sound you desire.
To achieve a natural sounding emulation of a big room
with long decay, select “Large”. Use the Medium and
Small settings accordingly for simulations of smaller
rooms.
Again: Building the perfect guitar sound is not always
about doing the most obvious. You may find cool settings
by swimming against the stream.
Hi Col & Lo Col – (High Color/Low Color)
Hi Color range:
Wool, Warm, Real, Clear, Bright, Crisp and Glass.
Lo Color range:
Thick, Round, Real, Light, Tight, Thin, NoBass
These parameters give you six variations of the reverb’s
72
EFFECTS – REVERB & EQ
low and high frequency ranges.
The two Color parameters can really change the
characteristics and style of the reverb – from “dark” and
“ambient” to “crisp” and “bright”.
Hi Lev & Lo Lev – (High Level/Low Level)
Range: -25 to 25
Use the Hi Lev and Lo Lev parameters to emphasize or
attenuate the selected Hi and Lo Color types.
Early
Range: -100 to 0dB
This parameter sets the level of the reverb’s initial
reflections (early reflections).
EQ – Parametric
The G-System features a 3 band parametric equalizer.
You can use this EQ either to shape the sound of
individual presets or – in the Lock Mode set via Utility –
as a “master EQ”.
For each band, the following parameters are
available:
Gain
Range: -12dB to +12dB
Use this parameter to attenuate or boost the frequency
range selected with the Freq(uency) parameter.
RevLev – Reverb Level
Range: -100 to 0dB
This parameter sets the Level of the reverb’s diffuse field.
Freq
Range: 20Hz to 20kHz
This parameter sets the center frequency of the
frequency range that you want to attenuate or boost.
Diff – Diffuse
Range: -25 to 25
With this parameter, you can fine-tuning the density of
the reverb’s diffuse field. It is set automatically when you
select a Decay time and allows you to reduce flutter in
the diffuse field to an absolute minimum.
Width
Range: 0.1 to 4 octaves
This parameter sets the width of the frequency range
around the frequency specified by the Freq(uency)
parameter.
Mix
Range: 0 to 100%
This parameter sets the relationship between the dry
signal and the level of the effect in this Effect Block.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
OutLev – Output Level
Range: -100 to 0dB
This parameter sets the overall Output level of this Effect
Block.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
73
EFFECTS – NOISE GATE
Noise Gate
Introduction
A noise gate is used to attenuate the signal when you
don’t play your guitar. This way you can mute all that
hiss, hum and other noise coming from cables, old
pedals etc.
Of course a Noise Gate is not the ultimate solution to
noise problems. You should try to avoid noise in the first
place. Noise can be introduced by a number of factors.
Poor cables, poorly shielded single coil pickups and
power supplies placed too close to signal cables are
common problems that you can work around by
experimenting.
However, a certain amount of noise will always be
present in any guitar setup. The Noise Gate can help you
attenuate this noise when you are not playing. Be
careful, though, when setting the parameters Threshold
and Release Rate. Too high a Threshold setting may
result in the Gate not opening when you play the guitar
softly. If Release time is too slow, the attack phase of the
signal will be cut.
Optimum settings will vary depending on the signal
present on the G-System’s input, so you will most likely
need different settings for Clean and Overdrive sounds.
Mode
Range: Hard – Soft
This parameter determines the basic characteristics of
the Noise Gate, i.e. how fast it should attenuate/dampen
the signal when it falls below Threshold.
Threshold
Range: -60dB to 0dB
The Threshold point determines at what point the Noise
Gate should start dampening the signal.
To set this parameter, turn up the volume using your
guitar’s volume potentiometer, but do not play. Then turn
up the Threshold value from -60dB to the point when the
desired dampening is actually achieved.
74
If you configure the Noise Gate this way, you will need to
set the Max Damping parameter (see below) to a value
other than 0dB, as 0dB means “no damping”.
Max. Damping
Range: 0dB to 90dB
This parameter determines how hard the signal should
be attenuated when the signal level falls below the set
Threshold.
Now you might think that you should always go for
maximum dampening. However, consider the fact that
you should also strive for a smooth transition from the
“gated/attenuated” stage to the “open” stage. The more
dBs must be released when opening the Gate, the more
obvious the effect becomes. This means that you will
have to experiment to fine-tune the Noise Gate to your
sounds – there is no one-size-fits-all settings.
Speed – Release Speed
Range: 3dB/sec to 200dB/sec
The Release parameter determines how fast the signal is
released when the Input signal rises above the Threshold
point again. As a rule of thumb, this parameter should be
set to a fairly high value.

preset even if the Noise Gate is disabled.

APPENDIX – FREQUENTLY ASKED QUESTIONS
Question - No signal on output?
On some specific user presets there is no signal in the
output, although the Input VU-meter shows that signal is
entering the unit.
Answer
This can occur if you set the Insert loop to "on" without
having anything connected to it. Please set the insert
loop to "off".
Question - G-System directly into a combo?
Is it possible to use the G-System straight into the front
end of a small combo guitar amp without the use of a pre
amp?
Answer
Yes this is possible, if the amp is used as a "power amp".
If you need to use the drive of the combo, the pre-amp
section of the combo should be inserted in the Insert
loop of the G-System (loop 5) to take full benefit of the
post effects of the G-System.
Question - How do I adjust the Input level?
What is the proper way to adjust the input level on my
G-System? Should the meters be almost clipping?
Answer
You should leave some headroom (around 3dB) on the
Input meter to avoid internal DSP overloads.
A DSP overload can happen anytime though, depending
on how much you boost the signal inside the unit. If you
boost the signal too much internally, the LEDs will light
up, even though the input is not too loud.
You should be careful not to overloading the DSP. In
analog equipment, overloads can produce harmonic
distortion, which can make the sound "warmer". In digital
equipment overloading just degrades the sound and
creates loud clicks!
76
Question - Global bypass?
How can I bypass the G-System?
Answer
There is no Global Bypass parameter in the G-System.
But you can assign an 'empty' preset to any
customizable switch. The factory preset B9-5 is an “allbypassed” preset.
Question - Control of several GFX01
Can one single G-System board control several GFX01
(the 1 unit processing module that is mounted under the
G-System board itself)?
Answer
No, this is not possible. The G-System board can only
control one GFX01 unit. However, via MIDI the G-System
can send certain MIDI messages to other MIDI
compatible devices.
Question - Volume Min value
My expression pedal is set to control the Volume
parameter and though the Min. parameter is set much
higher than 0, the “heel-down” position is still equal to “off”.
Answer
This is intentional and how most people want the Volume
control to work. If you need a minimum value different
from “off” in “heel-down” position, we suggest you use a
volume/expression pedal with an adjustable minimum
value.
