IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, please read and observe the following:
Power Supply
Memory Backup
301
501b
• Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
• This unit contains a battery which powers the unit’s
memory circuits while the main power is off. When this
battery becomes weak, the message shown below will
appear in the display. Once you see this message, have the
battery replaced with a fresh one as soon as possible to
avoid the loss of all data in memory. To have the battery
replaced, consult with your retailer, the nearest Roland
Service Center, or an authorized Roland distributor, as
listed on the “Information” page.
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of interference.
352a
• This device may interfere with radio and television
exception. Do not use this device in the vicinity of such
receivers.
352b
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initiating a call, or while conversing.
Should you experience such problems, you should
relocate such wireless devices so they are at a greater
distance from this unit, or switch them off.
355
• To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
Additional Precautions
551
• Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have stored in the unit’s memory in another MIDI
device (e.g., a sequencer).
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored in another MIDI device (e.g., a
sequencer) once it has been lost. Roland Corporation
assumes no liability concerning such loss of data.
553
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
554
• Never strike or apply strong pressure to the display.
556
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
561
Repairs and Data
452
• Please be aware that all data contained in the unit’s
memory may be lost when the unit is sent for repairs.
Important data should always be backed up in another
MIDI device (e.g., a sequencer), or written down on paper
(when possible). During repairs, due care is taken to avoid
the loss of data. However, in certain cases (such as when
circuitry related to memory itself is out of order), we
regret that it may not be possible to restore the data, and
Roland assumes no liability concerning such loss of data.
4
• Use only the specified expression pedal (EV-5; sold
separately). By connecting any other expression pedals,
you risk causing malfunction and/or damage to the unit.
562
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.

Main Features
Powerful COSM Modeling Effects Built-In
Quick Settings
Features internal high-quality modeled effects, including
bass amp, overdrive/distortion, compressor/limiter, touch
wah, pedal wah, and more.
Each effect contains pre-programmed settings for each effect.
Creating the effect sounds you want is simple—just select the
preset settings for the effect you are using.
Internal Analog Bypass Circuitry
A Wide Variety of Effects
When bypass is activated, signals can be output without
passing through the AD/DA converter. Moreover, analog
signals also can be output without passing through the AD/
DA converter when only chorus or reverb/delay is used.
The GT-6B provides 35 different effects, from pro-quality
chorus, delay and reverb, to octave, defretter, synth-bass, a
newly developed Auto Slap, and numerous other effects.
Equipped with XLR Balanced Output
Connectors
The GT-6B features two XLR type output jacks, enabling you
to connect to PAs and recording decks. And not only can you
output in stereo, these can also be selected as monaural
outputs and direct outs.
Customize Function
The GT-6B’s internal Customize function lets you bring your
own sensibilities into play, and design totally new effects by
tweaking the settings for the “Overdrive/Distortion,” and
“Pedal Wah” effects.
The resulting creations can then be saved on the GT-6B as
“Custom” settings. (p. 52)
Expression Pedal/Expression Pedal
Switch and Control Pedal
The unit features an expression pedal and control pedal that
you can use in setting the functions in each patch. The
functions that can be assigned to the expression pedal vary
with each patch you select, allowing you to use it as a wah
pedal, volume pedal, or other kind of pedal.
Furthermore, you can use the pedal as an “expression pedal
switch” to control (turn on and off) the current effect by
firmly pressing down at the front tip. (p. 46)
Includes Digital Outs
The unit also includes digital out connectors (coaxial),
convenient for digital recording. (p. 58)
EZ Tone
The GT-6B includes thirty representative effect sounds used
for creating new sounds. Now it’s easy to select just the
sounds you like. (p. 16)
COSM (Composite Object Sound Modeling)
Composite Object Sound Modeling (COSM) is an
original sound modeling technology developed by
Roland, in which the many factors that make up the
original sound, such as the electrical circuitry, structural
characteristics, materials used, and acoustics, are
analyzed and then recombined to reproduce that same
sound.

Chapter 1 Playing Sounds
What is a Patch?
Numbers
When performing on your bass, you may select a variety of
different tones according to what and where you are playing.
The effects you want to use and the parameter settings (knob
positions) will vary depending on the tone.
You can store combinations, or “sets,” of volume level and
other of these parameter settings, and by using the pedals to
switch these sets, you can change tones instantly. Each of these
stored sets is called a “patch.” The GT-6B can store 80 “User
patches,” the content of which you can change as you like,
along with 40 “Preset patches” which cannot be changed or
overwritten. These 120 patches are divided into groups called
“banks,” with each bank containing four patches.
The number appears at the left side of the right display, and
is indicated by a numeral from “1” through “4.”
Selecting Patches
How to Switch Patches
Patches are switched by rotating the PATCH/VALUE dial
while in the “Play screen.” You can also switch patches by
pressing the PATCH pedals.
fig.01-10
Patches within each bank are distinguished by the patch
“number” (1-4).

Chapter 1 Playing Sounds
You can use pedals 1–4 to switch on and off the individual
effects that are used in a patch. Each pedal shows the names
of two effects; the effect that you are currently able to switch
on and off is indicated in the lower row of the right display.
You can also change these with [PEDAL ASSIGN] (p. 45).
Turning Off the Power
1. Before turning off the power, confirm the following.
• Is the volume on the GT-6B, your amp, and all other
connected devices turned down to the minimum level?
2. Turn off the power to the bass amp (power amp) and
other devices.
3. Turn the GT-6B’s power off.
Switching Patches by Specifying the Bank
and Number
The GT-6B has been set at the factory so that you can
switch patches using the PATCH/VALUE dial or the
PATCH
and PATCH
pedals, but you can change
the settings by switching patches directly with the bank
and number. For more detailed information, refer to p. 60.

Chapter 2 Creating You Own Favorite Tones (Patches)
Getting the Tones You WantFast (EZ Tone)
Adjusting the Tones with the
Knobs
In addition to tones (patches) that you can actually use in
performances, the GT-6B also features internal sample
settings that are very useful when you want to create such
tones on your own. This feature is called “EZ Tone.”
The GT-6B panel features fifteen knob controls. These knobs
let you make changes to the selected patch’s tone quickly and
easily.
Using the EZ Tone function lets you quickly find tone
settings similar to the ones you want to create.
* There are also other methods you can use to adjust the tone.
For more details, refer to p. 19.

COMP ATK (Compressor attack)
1. Press [EZ TONE].
2. Rotate the VALUE dial to select the settings resembling
those for the tone you want.
3. Press the ON/OFF buttons to turn effects on and off,
and turn the knobs to adjust the tone.
This gives you a strong attack from picking when “BOSS
Comp”, “D-Comp” is selected as the type. The attack
becomes sharper as you turn the knob to the right, giving a
sound with greater bite.
LIMITER THR (Limiter threshold)
This adjusts the volume level at which the limiter is activated
when “Rack 160D” is selected as the type. As the knob is
turned to the left, the limiter effect is apparent at lower
volume levels.
fig.02-02
When “Vtg Rack U” is selected as the type, this adjusts the
volume of the sound input to the limiter. The effect becomes
deeper as you turn the knob to the right.
COMP SUS (Compressor sustain)
ON/OFF button
* You can press [EZ TONE] again to compare the tone in use
before entering EZ Tone mode with the present tone.
4. Press [EXIT] to return to the Play screen.
The tone switches to the tone selected in EZ Tone.
* Pressing [EXIT] while the readout is flashing (when the tone
prior to switching to EZ Tone mode is selected) returns you to
the patch that was selected before going into EZ Tone mode.
* If you want to save a tone you’ve created, use the Write
procedure (p. 23) to save it to a User patch.
16
This adjusts the amount of sustain when “BOSS Comp”, “DComp” is selected as the type. More of the effect is added as
you turn the knob to the right, lengthening the sustain time,
while also bringing out noise that occurs when you are not
playing the instrument.
LIMITER RATIO
This adjusts the limiter’s compression ratio when “Rack
160D” or “Vtg Rack U” is selected as the type. The
compression gets stronger as the knob is turned to the right.
* By pressing [TYPE VARIATION], you can then switch the
COMP/LIMITER type.
Chapter 2 Creating You Own Favorite Tones (Patches)
COMP/LIMITER LEVEL
SPEAKER
Adjusts the compressor/limiter volume level. The volume
increases as the knob is turned to the right.
Selects the speaker type.
OD/DIST DRIVE (Overdrive/Distortion Drive)
OD/DIST LEVEL (Overdrive/Distortion Level)
Adjusts the volume of the overdrive or distortion sound. The
volume increases as the knob is turned to the right.
* By pressing [TYPE VARIATION], you can then switch the
OVERDRIVE/DISTORTION type.
CHORUS LEVEL
Adjusts the volume of the chorus sound. The chorus sound
increases as the knob is turned to the right, deepening the
effect.
REV/DLY LEVEL (Reverb/Delay Level)
Adjusts the volume level of the reverb or delay sounds. The
reverb or delay sound increases as the knob is turned to the
right.
Only the reverb sound is adjusted when Fx Select (p. 27) is
set to R&D (Reverb&Delay). When SOS (SoundOnSound) is
selected, this adjusts the playback level.
PREAMP TYPE
Selects the preamp type.
PREAMP GAIN
Adjusts the amount of amplification for the preamp, which
changes the degree of distortion. The distortion gets stronger
as the knob is turned to the right.
PREAMP TREBLE
Adjusts the sound quality of the preamp’s upper range. The
high frequencies are boosted as the knob is turned to the right.
PREAMP MIDDLE
Adjusts the sound quality of the preamp’s midrange. The
midrange frequencies are boosted as the knob is turned to
the right.
PREAMP BASS
Adjusts the sound quality of the preamp’s lower range. The
low frequencies are boosted as the knob is turned to the right.
PREAMP LEVEL
Adjusts the preamp volume level. The volume increases as
the knob is turned to the right.
In addition, when [SELECT] is pressed, the PREAMP knobs
then function as control knobs for adjusting the 3-band
parametric EQ.
The adjustment screen for each band (LOW, MID, HIGH)
appearing in the display alternates each time you press
[SELECT]. You can adjust the Q, frequency, and gain for each
band.
Q
This adjusts the Equalizer bandwidth (the range of frequencies
affected by that EQ control). The bandwidth is narrowed as the
knob is turned to the right, resulting in a more notched
equalization. Use higher Q settings to affect specific
frequencies and give the tone particular qualities. Conversely,
the bandwidth becomes broader as the knob is turned to the
left. Use lower Q settings when you want to adjust the overall
low end or high end and change the overall tone.
FREQ (Frequency)
Adjusts the center frequency for the equalizer. The frequency
(upper range) increases as the knob is turned to the right.
GAIN
Adjusts the volume level for the equalizer adjusted with the
Q and FREQ settings above. The volume level for the
frequency range is boosted more as the knob is turned
further to the right of center; turning the knob to the left of
the center position cuts those frequencies.
TOTAL (Total Gain)
Adjusts the overall volume level of the 3-band equalizer. The
overall volume level is boosted more as the knob is turned
further to the right of center; turning the knob to the left of
the center position cuts those frequencies.
EFFECT LEVEL
Adjusts the overall effect volume level. The volume increases
as the knob is turned to the right.
* When the Bypass EXP Mode (p. 55) and Noise Suppressor (p.
44) is set to “Off,” only CHORUS or REV/DLY is used, so
turning this knob does not change the volume of the direct
sound.
When you want to save a tone created with EZ Tone, or
changed with the knob controls, use the Write procedure
(p. 23) to save the tone to a User patch.

Chapter 4 The Effects Explained
This chapter describes the particular qualities of each of the
GT-6B’s internal effects, as well as the parameters used to
control them.
Rack 160D
Models the dbx 160x.
Vtg Rack U
Models the UREI 1178.
Attack
The sound that is input to each effect is called the “direct
sound,” and the sound modified by the effect is called
the “effect sound.”
Sustain
COMP/LIMITER
(Compressor/Limiter)
The compressor is an effect that compresses (or attenuates)
loud input levels and expands (boosts) low input levels, thus
evening out the volume to create sustain without distortion.
It also has the effect of evening out the sound.
The limiter is an effect that prevents distortion by
suppressing input signals that exceed a set value (threshold).
You can get the same effect achieved with the compressor by
setting the threshold at a low value.
The GT-6B’s COSM technology provides you with four types
of modeled compressor/limiter perfectly suited for the bass.

Type

(with BOSS Comp, D-Comp)
Boosts low-level signals, adjusting the time over which
sounds are sustained. Higher values deepen the effect,
resulting in a longer sustain.
Threshold
(with Rack 160D, Vtg Rack U)
Adjust this as appropriate for the input signal from your
bass. When the input signal level exceeds this threshold
level, limiting will be applied. The limiter goes onto effect at
lower levels as the value is reduced with Rack 160D.
This controls the input level with Vtg Rack U. Increasing the
value deepens the effect.
(“Thres (input)” appears in the display.)
Ratio
(with Rack 160D, Vtg Rack U)
Adjusts the limiter compression ratio. Higher values create a
stronger compression effect.
Release
(with Vtg Rack U)
This adjusts the time from when the signal level drops below
the threshold until when the compression is removed. The
higher the values set, the more rapidly the compression is
released, and the more clearly the sound from the next string
played is heard.
Tone
(with BOSS Comp)
Adjusts the tone. The higher the value set, the more the high
frequencies are boosted, resulting in a harder sound.
Level
Adjusts the volume.
BOSS Comp
Models the BOSS CS-3
D-Comp
Models the MXR dyna comp.

document are intended to be descriptive in nature, used
solely to identify the equipment whose sound is
simulated using COSM technology.
(with BOSS Comp, D-Comp)
Adjusts the strength of the picking attack when the strings
are played. Higher values result in a sharper attack, creating
a more clearly defined sound.
(with Vtg Rack U)
This adjusts the amount of time that is to pass between the
point at which the input level exceeds the set threshold level
and compression begins, and the time at which the
compression ratio set with the Ratio setting is achieved.
Compression is applied more rapidly as the value is
increased.
Chapter 4 The Effects Explained
OD/DIST (Overdrive/Distortion)
This effect distorts the sound to create long sustain. The GT6B provides nine types of distortion with two different
custom settings.
■ OD: Overdrive
This provides the warm, natural type of distortion that
occurs naturally when you turn up the volume on a tube
amp. This effect is often used as an amp pre-booster.
■ DST: Distortion
This effect features a deep, powerful distortion that is
difficult to achieve with amp distortion alone.
■ FUZ: Fuzz
This effect gives an even more powerful and intense
distortion than you get with regular distortion.

CHORUS
Pre Delay
This is an effect that adds a slightly detuned sound to the
original bass sound, resulting in a beautiful sound with
greater depth and breadth. Developed by BOSS, this is one
effect that is popular the world over.
Low Cut
* When the Bypass EXP Mode (p. 55) and Noise Suppressor (p. 44)
is set to “Off” and only CHORUS or REV/DLY is used, the direct
sound is output as analog output.

The low-cut cuts the frequencies in the chorus sound that are
below a specified frequency. When the low end of the chorus
sound is cut so that the chorus is applied only to the higher
frequencies, the chorus sound appears only in the harmonics,
without any modulation of the fundamental frequencies,
creating a great sound effect for the bass. This setting adjusts
the frequency at which the low-cut begins to take effect.
When “Flat” is selected, the low-cut has no effect.
Effect Level
This adjusts the volume level of the chorus sound that is
mixed with the direct sound. The effect deepens as the value
is increased.
On/Off (Effect On/Off)
Sets the chorus effect to ON or OFF.
Mode
Selects the chorus mode.
Mono:
Chorus with the same sound output from both the left and
right channels.
Stereo:
This is a stereo chorus effect that adds different chorus
sounds to the left and right channels.
Rate
Adjusts the rate of the chorus effect.
* When set to BPM, the value of each parameter is set according
to the value of the Master BPM (p. 44) specified for each patch.
This makes it easy to achieve effect sound settings that match
the tempo of the song (synchronizing the cycle to one-half or
one-fourth of the BPM when the set cycle rate is increased).
When setting to the BPM, press PARAMETER [
] to
display the Master BPM settings screen.
Depth
Adjusts the depth of the chorus effect. To use it for doubling,
set the value to “0.”
Doubling
With doubling, a slightly delayed sound (short delay
sound) is added to the original sound, creating an effect
that sounds like two people playing simultaneously
(multiple sounds played), for an effect with greater depth.
REV/DLY (Reverb/Delay)/
SOS (Sound On Sound)
You can select and use the reverb/delay or Sound On Sound
with Fx Select.
* When the Bypass EXP Mode (p. 55) and Noise Suppressor (p.

Normal:
This is a regular ring modulator effect.
Intelligent:
The oscillator frequency changes according to the pitch of the
input sound, yielding a sound with more distinct changes in
pitch, something that differs from the effect you get with the
“Normal” setting. This effect won’t sound right unless the
pitch of the bass is detected correctly. So it’s best to use this
effect only when playing notes one at a time.

This produces a flanging effect that gives a sort of “twisting”
character to the sound. Although it resembles the phaser
effect, the flanger yields a colder, more metallic twisting
effect.

Wave
This selects the type of waveform used as the foundation of
the bass synthesizer.
Square:
A “square wave (
sound generator.
)” is produced by the internal
Saw:
A “saw wave (
generator.
)” is produced by the internal sound
Brass:
Waveform shaping outputs a soft sound with a fast attack
and a sharp edge.
42
Chapter 4 The Effects Explained
Bow:
Waveform shaping outputs a soft sound with no attack.
Octave Shift
(with Square and Saw)
This outputs sound one octave below the original sound.
PWM Rate (Pulse Width Modulation Rate)
(with Square)
Modulation is applied to the waveform (Square wave only)
to create a broader, fatter sound. Higher values increase the
rate of the modulation.
PWM Depth (Pulse Width Modulation Depth)
Resonance
This adjusts the filter resonance (the amount of feedback).
Increasing the value emphasizes the effect, creating a more
unusual sound.
Cutoff Freq (Cutoff frequency)
This adjusts the frequency at which the harmonic
components are cut off (the cutoff frequency). This parameter
determines the tone at the point that the filter movement
finally stops.
Depth
This adjusts the noise added to the sound from the sound
generator. Adding noise gives the synth bass a special type of
ambience.
This adjusts how much the filter shifts. When a positive
value is set, playing a string causes the filter to go upwards,
starting from the conditions determined with the cutoff
frequency. Conversely, the movement is downward when
the value is negative. The change becomes more dramatic as
the numerical value is increased.
Sens
Decay
This adjusts the input sensitivity.
In Internal Sound Generator method, although the response
of the internal sound generator improves as the sensitivity
value is increased, errors occur more often. Try to set the
value as high as possible without causing errors.
In Waveform Shaping method, this lets you adjust the
sensitivity of the shifting filter in response to the strings as
they are played when the attack trigger is turned off. Raising
this value allows the filter to respond with greater sensitivity,
even when the strings are played softly.
(with Square and Saw, or Attack Trig On)
This sets the rate for the filter’s movement. The filter moves
more slowly as the value is increased.
Hold
(with Square, Saw)
You can use the expression pedal to control the frequency of
sounds from the internal sound generator.
Use this by setting the parameter to “On” and assigning the
expression pedal or similar controller to Pdl Position.
Noise Level
(with Square and Saw)
This sustains the sound output by the sound generator. You
can use a control pedal or other such control to hold synth
bass sounds at the same pitch at which they are played.
* When using the Hold function, be aware of the importance of
the order in which the effects are connected. When the noise
suppressor is connected after FX-2, held synth sounds are not
output when the bass input sound is stopped. In such cases, be
sure to place FX-2 ahead of the noise suppressor (p. 22).
Synth Level
This determines the volume of the synthesizer sound.
Direct Level
Adjusts the volume of the direct sound.
Bend
Pitch Min
(with Square, Saw)
Sets the pitch produced when the expression pedal is
released.
Attack Trig (Attack Trigger)
Pitch Max
(with Brass and Bow)
This setting determines whether the filter acts according to
the envelope of the input sound or mechanically by detecting
the vibration of the strings as they are played. When set to
OFF, the filter operates in response to the volume of the
input bass sound, like a touch wah; when set to ON, the filter
operates more mechanically, as with the Internal Sound
Generator method, by detecting the degree of attack.
Pdl Position (pedal position)
(with Square, Saw)
Sets the pitch produced when the expression pedal is fully
depressed.
(with Square, Saw)
Adjusts the Pedal Bend pedal position.
43
Chapter 4
(with Square)
This adjusts the PWM depth. When set to “0,” no PWM effect
is obtained.
* When using the synth bass with this parameter on, errors may
occur if the unit is unable to detect the attack properly.
Completely mute the other strings, and play single notes.
Chapter 4 The Effects Explained
NS: Noise Suppressor
This effect reduces the noise and hum picked up by the bass.
Use this when noise that occurs when you are not playing the
bass becomes noticeable. Since it suppresses the noise by
monitoring the volume level of the actual bass sound being
input, it always gives a natural effect.

Master BPM Tap Input
You can use the CTL pedal to set the Master BPM by
means of tap input.
Depress the CTL pedal two or more times in time with
the performance’s tempo, and the Master BPM is set to
match the timing you’ve used while depressing the
pedal.
To use the CTL pedal and tap tempo to set the Master
BPM, set Pedal Assign as follows:

Adjust this parameter as appropriate for the volume of the
noise. If the noise level is high, a higher setting is
appropriate. Use a lower setting when the noise level is low.
* High threshold settings may prevent sounds from being
output when you play with your bass volume turned down.
Release
Adjusts the time from when the noise suppressor begins to
function until the noise level reaches “0.”
This is a volume control effect.
This is normally controlled with the expression pedal.

direct sound is output as analog output. In this case, EFFECT
LEVEL does not change the volume of the direct sound.
Master BPM
Adjusts the BPM value for each patch.
* BPM (beats per minute) indicates the number of quarter note
beats that occur in one minute.
* When you have an external MIDI device connected, the
Master BPM is synchronized to the external MIDI device’s
tempo, so you cannot set the Master BPM. If you want to be
able to set the Master BPM, set the “MIDI: Sync Clock” (p.
65) to Internal.

FV: Foot Volume
* Note the following points when Bypass EXP Mode (p.55) is
set to “Off.”
• Analog bypass sound is output when all effects are
set to “OFF,” and the volume level cannot be
controlled using the Foot Volume.
• When CHORUS or REV/DLY are the only effects
being used, only the analog bypass sound is output
for the direct sound, so only the effect sound's
volume level is controlled with Foot Volume.

Chapter 8 Convenient Features of the GT-6B
Outputting Sounds Without
Effects Applied (Bypass)
Switching Bypass On and Off
The GT-6B features bypass circuitry. By using the bypass, the
signal path, from input to output, consists entirely of analog
circuitry. To switch to bypass, carry out the following
procedure.
When the BYPASS/CTL pedal or the expression pedal
switch function is set to “Bypass,” these pedals then toggle
between “bypass” or “effect on” each time they are pressed.
Using the Expression Pedal Even
When Bypass Is in Effect
You can use Bypass EXP Mode to set the routing of the
signals when bypass is in effect; these settings can be made
separately for each individual patch.
1. Press [NAME/NS/MASTER] until “Bypass EXP Mode”
appears in the display.
* Each time [NAME/NS/MASTER] is pressed, the item that
can be set is changed, following this order:
Name → Noise Suppressor → Master → Bypass EXP Mode
→ Foot Volume → Effect Chain.

bypass mode (refer to “Settings for Using the Expression
Pedal Switch/CTL Pedal”: p. 46).
Using the Buttons
Each time the panel button [TUNER/BYPASS] is pressed, the
unit switches between “Tuner mode (p. 56),” “Bypass mode”
and “Play mode.”
Connecting Directly to a Recording Mixer
or PA Mixer (XLR Balanced Output)
The GT-6B features balanced outputs that utilize XLR
connectors. Although direct boxes are generally used to
connect bass (effects processor) outputs to mixers in concert
halls and recording studios, you can connect the GT-6B
directly to the mixer, which lets you avoid degradations in
the sound quality, as well as any additional problems that
might occur as the result of connecting multiple devices.
fig.08-02
Chapter 7 Chapter 8
You cannot use the expression pedal while bypass is in
effect. The bypass sound does not pass through the AD/
DA converter, and analog bypass sound is output. The
analog bypass sound is also output for the direct sound
when only CHORUS or REV/DLY is used. (However,
the expression pedal affects only the effect sound.)
On:
You can use the expression pedal while bypass is in
effect. The bypass sound is output after passing through
the AD/DA converter. Also, the direct sound is output
after passing through the AD/DA converter even when
CHORUS or REV/DLY is used, so you can use the
expression pedal to control the volume level for sounds
including the direct sound.
3. To save the settings, perform the Write procedure (p. 23).
Press [EXIT] to return to the Play screen.
Switching the XLR Output
Connector Signals
You can select the signals to be output from the XLR
connectors with the OUTPUT SELECT switch on the rear
panel.
R-OUTPUT-L: Stereo Output
The GT-6B’s stereo output is output as is, without change. Set
the switch to this position when recording in stereo or
sending stereo signals to a PA.
55
Chapter 8 Convenient Features of the GT-6B
DIRECT/MONO: Direct/Mono Output
Output from one of the connectors is the GT-6B’s stereo
output mixed to mono; the direct bass direct sound (the
analog bypass sound from the input jack) is output from the
other connector.
This switch setting determines whether the signals output
from the XLR output jacks are output in stereo (L/R) or as
direct mono output. Set the switch to this position when
using only one mixer channel, for example during concerts.
Additionally, for recording, you can record the direct bass
sound on a separate channel, then later on you can remix the
direct sound with the effect sound during mixdown.
Tuning the Bass
The GT-6B is equipped with an Internal automatic chromatic
tuner. Turning on the tuner mutes the output and activates
the tuner.
Turning the Tuner Function On
Use the following procedure to switch to Tuner mode.

connected devices match. If the MIDI channel settings are not
correct, the GT-6B will be unable to exchange data with other
MIDI devices.
Operating From the GT-6B
Outputting Program Change Messages
When a patch is selected on the GT-6B, a Program Change
message corresponding to the patch number is transmitted
simultaneously. The external MIDI device then switches its
settings according to the Program Change message it receives.

About MIDI
MIDI is an acronym for Musical Instrument Digital Interface,
and is a world-wide standard for allowing electronic musical
equipment to communicate by transmitting messages such as
performance information and sound selections. Any MIDI
equipped device is able to transmit applicable types of data
to another MIDI equipped device, even if the two devices are
different models or were made by different manufacturers.
In MIDI, performance information such as playing a key or
pressing a pedal are transmitted as MIDI Messages.
How MIDI messages are
transmitted and received
First, we will explain briefly how MIDI messages are
transmitted and received.
MIDI connectors
The following types of connector are used to convey MIDI
messages. MIDI cables are connected to these connectors as
needed.
fig.11-101
fig.11-102
Broadcasting
Station A
T.V. information from many different broadcasting station is
sent through an antena.
Broadcasting
Station B
Broadcasting
Station C
Select the channel of the
broadcasting station you
wish to watch
MIDI has sixteen channels 1 – 16, and MIDI messages will be
received by the instrument (the receiving device) whose
channel matches the channel of the transmitter.
* If omni mode is on, data of all MIDI channels will be received
regardless of the MIDI channel setting. If you do not need to
control a specific MIDI channel, you may set Omni On.
Main types of MIDI message
used by the GT-6B
MIDI includes many types of MIDI messages that can convey
a variety of information. MIDI messages can be broadly
divided into two types; messages that are handled separately
by MIDI channel (channel messages), and messages that are
handled without reference to a MIDI channel (system
messages).
Channel messages
MIDI IN:
This connector receives messages from another
MIDI device.
MIDI OUT:
This connector transmits messages from this
device.
MIDI THRU: This connector re-transmits the messages that
were received at MIDI IN.
* The GT-6B features both “MIDI IN” and “MIDI OUT”
connectors.
MIDI channels
MIDI is able to independently control more than one MIDI
device over a single MIDI cable. This is possible because of
the concept of MIDI channels.
These messages are used to convey performance
information. Normally these messages perform most of the
control. The way in which a receiving device will react to
each type of MIDI message will be determined by the
settings of the receiving device.
Program change messages
These messages are generally used to select sounds, and
include a program change number from 1 to 128 which
specifies the desired sound.
Control change messages
These messages are used to enhance the expressiveness of a
performance. Each message includes a controller number,
and the settings of the receiving device will determine what
aspect of the sound will be affected by control change
messages of a given controller number.
The specified parameters can be controlled with the GT-6B.
Appendices
The idea of MIDI channels is somewhat similar to the idea of
television channels. By changing channels on a television set,
you can view a variety of programs. This is because the
information of a particular channel is received when the
channels of the transmitter and receiver match.
71
Appendices
System messages
Factory Settings
System messages include exclusive messages, messages used
for synchronization, and messages used to keep a MIDI
system running correctly.
Tuner
TUNER Pitch:
A= 440 Hz (p. 57)
Exclusive messages
Exclusive messages handle information related to a unit’s
own unique sounds, or other device-specific information.
Generally, such messages can only be exchanged between
devices of the same model by the same manufacturer.
Exclusive messages can be employed to save the settings for
effects programs into a sequencer, or for transferring such
data to another GT-6B.
The two instruments must be set to the same device ID
numbers when exchanging SysEx messages.
About the MIDI implementation
MIDI allows a variety of messages to be exchanged between
instruments, but it is not necessarily the case that all types of
message can be exchanged between any two MIDI devices.
Two devices can communicate only if they both use the types
of messages that they have in common.
Thus, every owner’s manual for a MIDI device includes a
“MIDI Implementation Chart.” This chart shows the types of
message that the device is able to transmit and receive. By
comparing the MIDI implementation charts of two devices,
you can tell at a glance which messages they will be able to
exchange. Since the charts are always of a uniform size, you
can simply place the two charts side by side.

Restoring the Factory
Settings (Factory Reset)
Restoring the GT-6B to the settings made at the factory is
referred to as “Factory Reset.”
Not only can you return all of the settings to the values in
effect when the GT-6B was shipped from the factory, you can
also specify the range of settings to be reset.

Troubleshooting
If there is no sound, or if the GT-6B does not function as you
expect, first check the following points. If the measures in
this checklist do not resolve your problem, you should
contact your dealer or the nearest Roland Service Center.
No sound / Volume is weak
❍ Are the connection cables broken?
→ Try exchanging the connection cable.
❍ Is the GT-6B correctly connected to the other devices?
→ Check connections with the other devices (p. 12).
I Can’t Change Patches
❍
Is something other than the Play screen shown in the
display?
→ On the GT-6B, patches can be selected only when the
Play screen is displayed. Press [EXIT] to return to the
Play screen (p. 10).
Parameters specified with control
assign can’t be controlled as intended
❍ Is the effect switched off?
→ To control a parameter using the expression pedal or
CTL pedal, make sure the effect that contains the
parameter you intend to control is switched on.
❍
Is the connected amp/mixer turned off, or the volume
lowered?
→ Check the settings of the connected device.
❍ Is the EFFECT LEVEL knob lowered?
→ Adjust the EFFECT LEVEL knob to an appropriate
position (p. 17).
❍
Is something other than “Assignable” selected for the
SUB CTL 1,2 function setting?
→ When operating a foot switch connected to the SUB
EXP/SUB CTL 1, 2 jack, set the SUB CTL 1, 2 function to
“Assignable.” (p. 63)
❍
❍ Is Tuner/Bypass set to ON?
→ The direct sound is not output by setting the Tuner/
Bypass to “On” (p. 56).
Do the MIDI channel settings of both devices match
(when using MIDI)?
→ Make sure that the MIDI channels of both devices match
(p. 65).
❍ Is each effect set correctly?
→ Use the “Meter function” (p. 59) to check the output level
of each effect. If there is an effect for which the meter is
not moving, check the settings for that effect.
* When “Omni On” is selected in Omni mode, messages on all
MIDI channels are received, regardless of the MIDI channel
settings (p. 65).
→ Make sure that the controller numbers of both devices
match (p. 66).
❍
Is “FV: Level” or “MST: Effect Level” specified as a Pedal
Assign Target?
→ Carry out the operation in accordance with the source.(p.
50)
Volume level does not change with
Foot Volume
❍
The volume level of the instrument
connected to INPUT jack is too low:
❍
Could you be using a connection cable that contains a
resistor?
→ Use a connection cable that does not contain a resistor.
74
Is “OFF” selected in Bypass EXP Mode (p. 55) and Noise
Suppressor (p. 44)?
→ If “OFF” is set in Bypass EXP Mode, note the following:
• When all effects are set to OFF, the analog bypass sound
is output, and the volume cannot be controlled with Foot
Volume (p. 44).
• When CHORUS or REV/DLY are the only effects being
used, analog bypass sound is output for the direct
sound, so only the effect sound is controlled with the
FOOT VOLUME (p. 44).
Appendices
MIDI messages are not transmitted/
received
❍ Is the MIDI cable broken?
→ Try using a different MIDI cable.
❍
Is the GT-6B correctly connected to the external MIDI
device?
→ Check connections with the other MIDI device.
❍ Do the MIDI channel settings of both devices match?
→ Make sure that the MIDI channels on both devices match
(p. 65).
