(4.1.2) Basic Operations
Important: The sequence of blocks in your signal chain is not necessarily reflected in the footswitches. You can
freely assign blocks to available footswitches without changing your signal chain at all—and vice versa. See (4.6.1)
Hardware Assign > Footswitches to learn about this.
To assign a block (amp, cab, impulse response, effect, or clone) to an empty slot, tap the () icon and then use
the list that appears. See (4.3.1) Rigs > Creating a New Rig to learn about this.
To show a block’s Detailed Settings screen, double-tap it. Its settings screen will appear with its preset menu,
parameters, and assigned color. See (4.4) Adjusting Settings to learn about this.
To rearrange the blocks in your signal chain, tap and drag a block to another slot or
between two other blocks (the blocks after that position will shift one slot further down
the signal chain).
To activate or deactivate a block, press the footswitch assigned to it, or tap the block
and then tap the On/Off button that appears at the bottom of the screen.
To switch an amp, cab, or IR between a dual and single configuration, tap the amp,
cab, or IR, then tap the X2 button that appears at the top of the screen. See (4.1.4)
Amp/Cab Doubling to learn about this.
10
To remove a block, tap and hold the block, and then drag it to the bottom bar.
To load another rig (preset), do any of the following:
• Tap the  or  next to the name of the current rig on the
screen.
• Tap the name of the rig on the screen and then turn the
encoder.
• Hold the horizontal line below the rig name and drag
downwards until a rig list is shown, then tap a rig to load
it. When this list is shown, you can use the search bar to
help find a specific rig quickly.
To view other options, tap the menu icon in the upper-left corner, and then tap an option.
(4.1.3) Reverb/Delay Tail Spillover
HeadRush Core features two types of Reverb/Delay Tail Spillover:
•
If you have reverb and/or delay effect(s) active on your rig and then switch to a different rig, the effect(s)
will continue to decay after switching to the second rig.
•
If you have a reverb or delay effect active on your rig and then bypass this effect, it will continue to decay
after it is bypassed.
To enable or disable Reverb/Delay Tail Spillover for the whole rig, tap Tail on the main screen.
Note: This feature will not work if you are using an effects loop or if USB Audio is enabled in the Global
Settings.
To enable or disable Reverb/Delay Tail Spillover for an individual effect,
double tap the effect in the Main Screen to access the effect’s settings
screen. Then change the effect’s Tails by tapping the Off and On buttons.
Note: Adjusting this parameter will not impact the Reverb/Delay Tail Spillover
setting for the whole rig.
11
(4.1.4) Amp/Cab Doubling
When switching an amp, cab, or IR between a single and dual
configuration using the X2 button, you can select from two
options:
•
Stereo-Doubling: When this option is selected, two
amps, cabs, or IRs are placed left and right within a
single slot to create a wider image. Both amps, cabs,
or IRs will be active at all times.
•
Switch-Doubling: When this option is selected, two
amps, cabs, or IRs are placed within a single slot, and
you can switch between the top and bottom amp, cab,
or IR.
To use Switch-Doubling, you must assign a
footswitch to this function in your rig. In the Hardware
Assign page, select the Signal Chain category of the
Footswitch Assignment Menu, and choose from the
following two options:
Doubling: A <Switch> B: If there is one SwitchDoubled amp, cab, or IR, this setting assigns the
footswitch to alternate between the top and
bottom options of the block(s).
Both: A-B-C-D: If there are two Switch-Doubled
amps, cabs, or IRs, and one is located on the top
path of a split signal chain and the other is located
on the bottom path of a split signal chain, this
setting assigns the footswitch to alternate between
the four options of the block(s) in round-robin
order.

13
(4.3) Rigs
When you are using HeadRush Core, a rig is a preset: the combination of assigned blocks—the amps, cabs, IRs,
clones, and effects—and the parameter settings of each of them. You can create, edit, save, and load rigs, making
it easy to recall the perfect sound for each part of your performance.
To access your rig from the Menu, tap the My Rig icon.
Each rig has 14 slots, each of which can have one block (amp, cab, IR, clone, or effect) assigned
to it. An exception is when a slot is using an amp, cab, or IR in a dual configuration (when the 2X
button next to it is enabled).
Assigned slots will show graphical representations of the blocks, and empty slots will show a 
symbol.
(4.3.1) Creating a New Rig
To create a new rig, tap the  button in the upper-right corner of the main screen, and then tap
New Rig.
To assign a block (amp, cab, IR, clone, or effect) to an empty slot:
1. Tap the empty slot ().
2. In the list that appears, tap the type of block you want to assign.
3. In the list that appears, tap the specific block you want to assign.
4. In the next list that appears, tap the preset you want to load for that block.
As you add blocks, you will notice the CPU meter in the top left screen fill up. There is no limit to
the number of the same type of blocks you can add; however, if this CPU meter reaches 100%,
you may experience some unwanted tonal side effects (popping, clicks, etc.).
If you are loading an impulse response (IR) file, you can select one that is truncated to 1024 samples, which are
less DSP-intensive, freeing up more resources to load and use additional blocks and/or IRs to your rigs.
To load a truncated IR, select the IR 1024 model instead of the normal setting (2048) when adding an IR to your rig.

(4.3.2) Signal Path
The signal path is the direction that the audio signal follows from your
guitar, through your 14 available blocks, and ends at the outputs of
HeadRush Core. You can easily reconfigure your signal path to best
suit your needs, especially when it comes to creating more complex
rigs.
To reconfigure the signal path, tap the arrow next
to the signal path button, located at the bottom of
the Main screen. An overlay with your available
signal chain routings will appear.
The following signal path options are available:
Guitar: Straight Path
This straight signal path is the default and the most common
for users that are creating non-complex guitar tones.
Guitar: Middle Split
This signal path splits in the middle and rejoins near the end.
This configuration is useful for using two types of effects (or
chains of effects) but want to keep their signals separate.
There are three separate Middle Split options:
• Middle Split 3-4-3 features three slots after the Input, an
eight-slot split Mix section, and then three slots before the
Output.
• Middle Split 5-3-3 features five slots after the Input, a sixslot split Mix section, and then three slots before the
Output.
Note: Middle Splits 3-4-3 and 5-3-3 use the same singal
path icon shape.
• Middle Split 7-2-3 features seven slots after the Input, a
two-slot split Mix section, and then three slots before the
Output.
See (4.4.2) Adjusting Settings > Parameters > Mix to learn
how to mix the split paths together.
15
Guitar: Immediate Split
This signal path splits immediately from the source and rejoins
near the end. Like the second configuration, this one is useful
for using two types of effects (or chains of effects)
independently, but it allows for more models in the split paths
and the rejoined one.
See (4.4.2) Adjusting Settings > Parameters > Mix to learn
how to mix the split paths together.
Guitar: Dual Straight Path
This straight signal path is the most common for users that
would like to connect two guitars simultaneously while
maintaining separate singal paths for each guitar. This can be
useful for making easy switches between electric and acoustic
guitars on stage or playing along with a friend. When using this
signal path type, the upper path uses the Combo XLR+1/4”
microphone input, and the bottom path uses the 1/4” guitar
input.
Vocals: Straight Path
This straight signal path is the most common for users that are
creating non-complex vocal tones.
16
Vocals and Guitar: Dual Path
These signal paths are the most common for users who want
to utilize effects for both guitar and voice.
There are three separate Dual Path options.
• Dual Path 7-7 features seven slots each for vocals and
guitar.
• Dual Path 4-10 features four slots for vocals and ten
slots for guitar.
• Dual Path 2-12 features two slots for vocals and twelve
slots for guitar.
Optimizing Your Signal Path
After adding blocks to a rig, you can use the touchscreen to arrange your selected blocks in any sequence, but you
may find that some configurations will sound better than others.
Here are some common model placement suggestions for creating great rigs with HeadRush Core:
•
Dynamics (e.g., compressors), filters (e.g., wah, pitch shifters), and volume pedals are generally placed
at the beginning of the signal chain. Alternatively, you can place volume pedals at the end of the signal
chain to provide a slight variance in functionality.
•
Gain-based effects (e.g., overdrive/distortion, fuzz) usually come next.
•
Equalization (EQ) is often used to shape the tonal characteristics of overdrive/distortion and fuzz effects,
so put an EQ after them. Alternatively, place it before them to shape the guitar’s general tone—cutting
unwanted frequencies—before the gain pedals.
•
Modulation effects like flangers, phasers, and chorus are typically placed next.
•
Time-based effects like delays and reverbs are generally placed in between the amp and cab blocks (to
simulate an amp’s built in FX loop), or near the end of the signal chain.
•
Amp models, cab models, IRs, and amp clones are often placed near end of the signal chain, although you
can place it wherever you want, depending on your needs.
17
Switching Between Paths
When using split path signal chains, you can use a footswitch or expression pedal to toggle or blend between each
path.
To toggle between split paths using a footswitch, use
the (4.6) Hardware Assign page to assign a footswitch to
this function in your rig. In the Hardware Assign page,
select the Signal Chain category of the Footswitch
Assignment Menu, and choose Path Mix: A <Switch> B.
Each press of the assigned footswitch will alternate
between the full top row split path in the rig being active
and the bottom row being muted, and vice versa. This
option can only be applied to split path rigs.
Note: You can also set this assignment as part of a Scene
by adjusting the Patch Switch parameter located at the
bottom of the Scene Assign page.
To blend between signal paths using an external expression pedal, use the (4.6) Hardware Assign page
to assign the external expression pedal to the Mix > A <Crossfade> B assignment.
(4.3.3) Stereo vs. Mono
The outgoing signal from HeadRush Core can be mono or stereo, depending on the models
in your rig, the signal path, and which outputs you are using. An indicator near the end of the
signal path indicates the current configuration.
The signal will be stereo if you do any one of the following:
•
Use any stereo effect model in your signal chain. Even if you have placed mono effect models after it. This
is possible because the mono effect is simply applied identically to both channels and not summed.
•
Use a split signal path, even if the split paths rejoin before the output.
•
Use a double-amp, double-cab, and/or double-IR configuration (i.e., if 2X is on).
The signal will be mono if you do all of the following:
•
Use no stereo effect models in your signal chain.
•
Use the linear (not split) signal path.
•
Use only single-amp and single-cab configurations (if you use an amp or cab model at all).
Alternatively, the signal will be mono if you do both of the following:
•
Use only the L/Mono output (of a stereo pair) on the rear panel.
•
Reduce the Rig Width output setting to 0%.
To adjust the width of the stereo field, tap the Out icon at the end of your signal path, and turn the third parameter
knob to adjust the Rig Width output setting. This affects stereo signals only, not mono signals. 100% uses the
full stereo field while 0% produces a mono signal.
18
(4.3.4) Saving a Rig
If you have made certain changes to a rig, you will see an asterisk () next to its name at the top of the screen,
indicating that you have changed the rig in some way and may want to save it.
You will see an asterisk if you have done any of the following:
•
assigned a block to the rig.
•
deleted a block from the rig.
•
moved a block in the signal path.
•
changed a block’s preset (see (4.4) Adjusting Settings to learn more).
•
made any change in the Hardware Assign screen (see (4.6) Hardware Assign to learn more).
Activating or deactivating a block, adjusting parameters on any screen, or using the expression pedal on any screen
will not cause the asterisk to appear. You can save these changes to this rig, save these changes as another rig,
or discard them altogether.
If the asterisk is shown and you try to load a different rig, you will be asked to select one of these options:
•
Cancel: This option returns to the previous screen without saving the current rig or loading a new rig.
•
Discard Changes: This option loads a new rig without saving any changes to the previous rig.
•
Save as a New Rig: This option lets you save the current rig as a new rig. In the screen that appears, use the
keyboard that appears to enter a name, and then tap Save. That rig will be saved, and the new rig will load.
•
Save Changes to Rig: This option saves any changes you made to the rig and then loads the new rig.
Note: Select Do not show this dialog again in the message to disable these confirmation messages. You can
re-enable them in the (4.21.1) Global Settings > General screen.
To save a rig while you are editing it, tap the Save icon in the
upper-right corner.

(4.4.2) Parameters
Listed below are some of the common parameters that you can adjust for each type of block. The block types
include amps, cabs, IRs, clones, effects, input settings, output settings, and mix settings (if you are using a split
signal path). See (4.4.3) Saving a Block Preset to learn how to save a preset after adjusting parameters.
Amp (HeadRush / Revalver)
The Amp category is a list of popular guitar and bass
amplifiers.
Preset: This is the current amp preset, which includes the
model, all its settings, and its color assignment.
Model: This is the amp model.
Amp Settings: These are the settings for the selected
amp model (different models may have more or fewer
settings).
Out Level: This setting adjusts the overall output level
of the amp model without affecting its tonal
characteristics.
Color: This is the assigned color, which will appear in
the Hardware Assign screen and the switch indicator
if the amp is assigned to a switch.
Cab (HeadRush / Revalver)
The Cab category is a list of popular guitar and bass amp
cabinets, which contain the speakers. HeadRush Core
recreates not only the sound of the cabinet but also the type
of microphone recording it.
Preset: This is the current cab preset, which includes the
model, all its settings, and its color assignment.
Cab Type: This is the cab type. Numbers notated as
_X__ indicate the number of speakers it has and the
size of each speaker (e.g., 2X12 denotes a cab with
two 12-inch speakers, 4X10 denotes a cab with four
10-inch speakers). Numbers notated as __W indicate
the emulated wattage (output power) of the speaker.
Mic Type: This is the type of microphone being used on the cab. You can select different models of dynamic
(Dyn), condenser (Cond), or ribbon (Ribbon) microphones.
Mic Settings: These are the settings for the microphone:
• Break Up: This determines the amount of speaker “breakup”—the natural distortion that occurs when the
audio signal overdrives the speaker.
• On-Axis: This determines the microphone position relative to the cab. On-axis placement (On) positions the
microphone at the center of the speaker, usually resulting in a brighter sound with more definition. Off-axis
placement (Off) is slightly offset at an angle from the center of the speaker, and it often sounds darker in tone.
• Out Gain: This is the cab’s output gain level.
• Amp Gain: This is the amplifier’s gain level.
Color: This is the assigned color, which will appear in the Hardware Assign screen and the switch indicator if
the cab is assigned to a switch.
22
Effects
There are many types of guitar and vocal effects available
on HeadRush Core, and their adjustable settings depend
on the type of effect selected.
Preset: This is the current effect preset, which includes
the selected effect, all its settings, and its color
assignment.
Effect Settings: After the effect has been selected, you
can further dial in the effect by adjusting the
parameters that appear on screen.
Amp and Pedal Clones
A Clone is an alternative type of guitar/bass amplifier or
distortion/overdrive/fuzz pedal simulation that allows you
to capture the sound of your own gear and use it inside of
HeadRush Core. See (4.15) Amp Cloner to learn more
about how to capture your own clones.
Preset: This is the current Clone preset, which includes
the selected clone, all its settings, and its color
assignment.
Clone File: Tap here to select a previously created or
imported clone from your internal storage.
Clone Settings: After the Clone has been selected, you
can further dial in the clone’s sound by adjusting the
tone stack parameters that appear on screen.
Cab ON/OFF: You can use this setting to disable the
sound of the speaker cab from your Amp & Cab
clone, and instead use an onboard cabinet model or
an IR file.
Speaker Cabinet Impulse Response (IR 2048/1024 Samples)
A Speaker Cabinet Impulse Response (IR) models the tone
and speaker characteristics of a guitar or bass speaker
cabinet, and is typically stored as a .WAV file.
These files can be loaded to your rig by using the IR (2048
Samples) and/or IR (1024 Samples) blocks, found in the
Cab/IR category of the model selector.
HeadRush Core includes 300+ cabinet IR files onboard,
however, there are also many reputable third-party companies
that capture and distribute IRs that can be imported into
HeadRush Core.
You can load IRs at the highest quality (2048 samples) or at a lower quality (truncated to 1024 samples), which is
less DSP-intensive, enabling you to load and use additional blocks and/or IRs to your rigs.
Preset: This is the current IR preset, including the selected IR, all its settings, and its color assignment.
IR File: Tap here to select a speaker cabinet IR file from your internal storage.
IR Settings: After the IR has been selected, you can further dial in the IR’s sound by adjusting the Gain, HiCut, Lo-Cut, and Mix parameters on screen.
23
Convolution Reverb Impulse Response (C-Verb)
A Convolution Reverb Impulse Response (IR) models the
reverberation and ambiance characteristics of an acoustic
space, and is typically stored as a .WAV, .AIF, or .OPUS
file.
These files can be loaded to your rig by using the C-Verb
effect, found in the Reverbs category of the model
selector.
The C-Verb effect allows you to explore your tone in a
variety of acoustic spaces using the included 50+ IR files or
by importing IRs from third-party companies for virtually
endless tonal possibilities.
Preset: This is the current C-Verb preset, including the selected IR, all its settings, and its color assignment.
Reverb File: Tap here to select a convolution reverb IR file from your internal storage.
IR Settings: After the IR has been selected, you can further dial in the IR’s sound by adjusting the High Pass,
Low Pass, Wet, and Tails parameters on screen.
Important: Only one instance of C-Verb can be loaded to each Rig. If a multi-channel IR is loaded, only the first two
channels are used. The maximum supported length for a loaded IR is 10 seconds, and the CPU usage of this effect
will be determined by the length of the IR loaded.

Control Change, Note On/Off) when the rig is loaded. See (4.6.5) MIDI Out Messages for more information about
this feature.
30
(4.6.1) Footswitches
The ten boxes in the lower-left corner represent the 2 footswitch
banks of HeadRush Core when in Stomp Mode or Hybrid Mode.
You can assign any switch-based parameters (ones with only two
states) to any of the footswitches—regardless of their location in
the signal chain.
You can also assign controls from the Looper, Metronome, and
Practice Tool features to a footswitch within a rig for easier
access.
To assign a parameter to a footswitch:
1. Tap a box.  indicates an empty box.
2. In the list that appears, tap the block or feature with the
parameter or control that you want to assign.
3. In the list that appears, tap the parameter you want to assign.
Usually, the parameter will simply be On (to activate or
deactivate it).
Tap Unassigned  to unassign that footswitch.
4. On the Hardware Assign screen, tap Latch/Momnt/Scene
for that footswitch to cycle through the available options:
When set to Latch, each press will turn the block on or off.
When set to Momnt, pressing and holding the footswitch will
activate it, and releasing the footswitch will deactivate it. This
will also disable the footswitch’s default hold functionality (for
example, entering the Looper for footswitch 4).
When set to Scene, each press will turn a scene on or off. A
scene is a collection of “linked” blocks in the rig—all of which
will simultaneously turn on or off when you press that scene’s
footswitch. See the (4.6.2) Scenes section to learn about this
feature.
To swap two assignments, tap and drag one of them over the
other, and then release it.

31
(4.6.2) Scenes
The Scene feature allows you to turn multiple blocks on or off or change multiple presets for a block in each rig
using one footswitch press. When you press the footswitch assigned to that scene, all blocks included in that scene
will turn on or off, depending on how you assign them. This is a great way to create multiple tones in the same rig.
For instance, you may want a particular reverb block to be on anytime a particular distortion block is also on.
Alternatively, you may want to turn one delay block off when you turn another one on. Scenes enable you to do this
with only one footswitch press.
To create and edit a scene:
1. On the Hardware Assign screen, tap Latch/Momnt/Scene for
the desired footswitch to cycle through the available options, and
select Scene.
2. On that footswitch, tap Edit. The Scene Editor will appear, which
shows all models in your rig.
3. For each model in the rig, tap the On/Off/No Change field to
cycle through the available options:
• On: This block will turn on when you turn the scene on.
• Off: This block will turn off when you turn the scene on.
• No Change: This model will remain unaffected when you turn
the scene on.
4. If you would like a block to load a preset when the scene is turned
on, tap the Preset field, and select a preset. With this feature
enabled, you change the parameters of a block by selecting a
scene.
5. If you are using Switch-Doubling or a Split Path signal chain, use
the Doubling Switch and Path Switch options to toggle between
A/B/No Change.
6. If you would like to set up a command of up to 5 different MIDI

(4.6.3) Expression Pedal
When an external expression pedal with a toe switch is connected, it can control two parameters (in Classic Mode),
two sets of four parameters (in Advanced Mode) or two sets of two parameters (in Auto-Engage Mode). Use the
external pedal’s toe switch to switch between them—Expression Pedal A or B.
Note: When you save your rig, the current selected Expression Pedal state (A or B) will be saved and then recalled
when you load the rig again.
The column of four boxes represents the expression pedal settings. You can assign one or
more continuously adjustable parameters (ones with a range of values) to the expression
pedal.
To set the expression pedal mode, tap the button above Range in the upper-right corner
to select Classic, Advanced, or Auto-Engage.
• Classic: You can assign one parameter to each expression pedal (A and B). Using
the toe switch will select the other expression pedal parameter and deactivate
(bypass) the current expression pedal’s parameter. For instance, if you assign a wah
pedal to Expression Pedal A and a volume pedal to Expression Pedal B, only one
of them will be active at any time; when you are controlling the wah pedal, the
volume pedal will be bypassed, and vice versa.
• Advanced: You can assign up to four parameters to each expression pedal (A and
B). Moving the pedal will adjust all its assigned parameters simultaneously. Using
the toe switch will select the other expression pedal and leave the current pedal’s
parameters active and at their maximum values.
• Auto-Engage: You can assign up to two parameters to each expression pedal (A
and B). In this mode, you can deactivate (bypass) the current expression pedal’s
parameter(s) by moving it to the Toe Up, Toe Down, or Stop position, depending
on your Off Pos (Position) setting. You can also set an Off Delay time (0–5000 ms)
that determines how long it will take for the parameter(s) to bypass when the
expression pedal is moved to the Off Position. Like in Classic mode, using the toe
switch will still select the other expression pedal (A or B) and deactivate (bypass)
the current expression pedal’s parameter(s).
Important: You cannot edit any parameters assigned to the expression pedal in Classic Mode
(they will show a lock icon and be grayed out in other screens to indicate this). You can edit any
parameters assigned to the expression pedal in Advanced Mode or Auto-Engage Mode (they
will show a pedal icon in other screens to indicate this).
33
To assign a parameter to the expression pedal:
1. If the Assign button is not on, tap it.
2. Tap a box under the Assign button.  indicates an empty
box.
3. In the list that appears, tap the model with the parameter
you want to assign.
4. In the list that appears, tap the parameter you want to
assign.
Tap Unassigned  to unassign that box.
To set the range of an assigned parameter:
1. If the Range button is not on, tap it.
2. Tap a value under the Range button.
3. Turn the encoder to set the desired value as a
percentage of the parameter’s entire range. Press the
encoder or tap elsewhere to confirm the value.
(4.6.4) Ext Amp
You can assign a switch to send a signal to your traditional guitar amplifier’s footswitch input by using the external
amp output. You can use this feature to do things like change from the clean to dirty channel or turn reverb on and
off on your amplifier.
To use this feature when switching to a rig, tap the button under Ext Amp on the hardware assign page, and then
select Tip, Ring, or Both. If you are unsure of which setting to use, please consult the amplifier's manual or
manufacturer to confirm.
This feature can also be assigned to a footswitch on the Model Selector page that appears when you are assigning
a footswitch’s function. It can also be assigned to a scene by adjusting the parameter on the Scene Editor screen.
IMPORTANT! Only connect this output to amplifiers that have a "short-to-sleeve" footswitch input. If you connect
this output to any other type of footswitch input, you may cause permanent damage to your equipment. If you are
unsure if your amplifier has a “short-to-sleeve” footswitch input, please consult the amplifier’s manual or
manufacturer to confirm.
(4.6.5) MIDI Out Messages

(4.15) Amp Cloner
The Amp Cloner feature enables you to clone the sound of a real guitar or bass amplifier or pre-amp (with or without
speakers), as well as real distortion, overdrive, and fuzz pedals, and expand the amount of available amp and effect
sounds in your HeadRush Core. However, please be aware that some pedals cannot be cloned:
• Certain gated fuzz pedals are not able to be cloned at this time. A “gated fuzz” doesn’t mean that there is an
actual noise gate in the fuzz pedal, but that the bias is shifted so hard, that the signal is cutting out on low input
volumes (which is a Noise Gate-like behavior).
• Some older fuzz pedals that were designed to be connected to a high-Z (high impedance) guitar output (7k to
15k Ohms) are not able to be cloned directly into the HeadRush Core without the use of a ReAmp box.
• Time-based effects like flanger, chorus, and delay effects are unable to be cloned at this time.
To access Amp Cloner, tap the Menu icon in the top
left of the Main screen, and then tap the Amp Cloner
icon.
Once Amp Cloner has loaded, you will be guided through an
easy 3 step process of preparing to clone your gear via the
on-screen directions shown below.
Once you are ready to clone your gear, tap Proceed to begin
the process.
1. In Step 1, you will choose the type of gear that you would like
to clone: Amp & Cab, Amp / Pre-Amp, or Pedal Only.
2. In Step 2, HeadRush Core will guide you through the process
of correctly connecting your Amp or Pedal to HeadRush
Core. During this step, you can tap the Connection Diagram
button to view a visual diagram and ensure that your
connections are correct. Additionally, you can preview and
set your signal level using the on-screen meter.
Tip: While we normally recommend targeting a signal level of
-6 db to -3 db, some amps may be cloned more accurately
when the signal level is closer to 0 dB. If you find that your
clone is lacking gain or body when compared to the target
amp, try aiming for a higher level. Likewise, if you find that
your clone has too much gain or body when compared to the
target amp, try aiming for a lower level.
51
3. In Step 3, you can match the on-screen controls to the
controls on the gear being cloned. Matching these controls
is helpful as they will be taken into consideration if you want
to adjust your EQ after the cloning process. Once you have
matched your controls, tap Start Clone to begin the
cloning process.
Once the cloning process has begun, a progress bar will be
shown with details about what’s happening. You will hear about
1 minute of measurement tones, and then the remaining time
will be spent processing the information. The entire process
lasts about 3 minutes or less; however, you can tap the Cancel
button to abort the process at any time.
After the cloning process is complete, you will be brought to a
screen where you are able to preview your clone, as well as
compare it to the target device you cloned. You may choose to
refine the clone at this time by tapping the Amp Controls
button.
While on this screen, you can make adjustments to the clone’s
sound. You can also switch between the sound of the new
clone and the target device.
Tip: If you are cloning an Amp & Cab, it is much easier to
compare the sound of your clone to the target Amp & Cab if
you place your HeadRush Core in a seperate room away from
the target Amp & Cab. This can help you listen more objectively
and not get distracted by any sound that you may still be able to
hear while using headphones and listening to the comparisons.
Once you have finished making any last adjustments, tap the
Confirm button. You will be brought back to the previous page.
Once you are finished, tap the Save button. After you have
saved your clone, you can add your clone to a rig in the same
way you would add a traditional amp model or effect pedal by
tapping an empty block on the Main page, and selecting Amp
Clone.

(4.16) USB
You can use HeadRush Core’s USB connection to your computer for (4.16.1) Transferring Files & Settings (e.g.,
rigs, setlists, presets, etc.), (4.16.2) Recording (to a digital audio workstation [DAW]), or (4.16.3) Reamping.
(4.16.1) Transferring Files & Settings
Over a USB connection, you can transfer rig, setlist, model
preset, loop, clone, and/or impulse response (IR) files between
your computer and HeadRush Core.
We recommend creating a backup copy of your files to your
computer before you make any changes.
Important:
Do not disconnect or power off HeadRush Core during the
process.
Any unsupported files will be ignored.
You cannot transfer a folder or .zip/archive folder to/from
HeadRush Core. Instead, transfer any supported files directly.
We recommend organizing the file structure of your rigs,
setlists, model presets, and/or impulse response files on your
computer so that it is identical to the file structure as shown on
the HeadRush Core “drive.”
To transfer files between HeadRush Core and your computer:
1. Connect your computer to HeadRush Core’s USB port using a standard USB cable.
2. With your computer powered on, power on HeadRush Core using the power switch.
3. Tap the Menu icon in the upper-left corner of the Main screen, and then tap USB Transfer.
4. On your computer, HeadRush Core will appear as a mass-storage device called HeadRush.
Windows users: If this is the first time you’ve connected it to this computer, you may need to wait a minute
while it installs the class-compliant drivers.
5. Open the HeadRush drive. You can now freely click and drag contents between HeadRush and your computer.
Note that any changes you make to the contents of your HeadRush are immediate and cannot be cancelled.
Tip: During this step, you can add an image to use with the screen lock feature. See (4.17) Lock Screen to
learn more.
6. IMPORTANT: When you are finished transferring contents, you must unmount/eject the HeadRush drive from
your computer. File corruption may occur if the drive is not properly ejected before continuing.
7. After the drive has been ejected, tap Sync on your HeadRush Core to "commit" any changes you made to the
contents of the HeadRush drive.
As HeadRush Core analyzes and imports the files, a meter on the display will indicate its progress. The normal
Menu screen will reappear when the process is finished. Do not disconnect or power off HeadRush Core during
the sync process.
53
(4.16.2) Recording
When HeadRush Core’s USB port is connected to your computer, you can select and use HeadRush Core as a 24bit audio interface, enabling you to play audio through it or to send its audio signal to the computer. It can use
sample rates of 44.1 kHz, 48 kHz, or 96 kHz.
Important Note for Windows Users: Before connecting HeadRush Core to your computer, download the
necessary drivers from support.headrushfx.com and install them.
To use HeadRush Core as an audio interface with your computer, open your computer’s Control Panel
(Windows®) or System Preferences (macOS®), open its sound/audio settings, and select HeadRush Core as the
device for recording/input and/or for playback/output.
HeadRush Core can send six separate audio signal channels to your computer. Before recording HeadRush Core’s
audio signal into your digital audio workstation (DAW), select the channel/channels you want to record:
1: the left channel of the XLR main outputs with all active effects applied.
2: the right channel of the XLR main outputs with all active effects applied.
3: the left channel of the 1/4” main outputs with all active effects applied.
4: the right channel of the 1/4” main outputs with all active effects applied.
5: a mono channel of the 1/4” guitar input with no effects applied.
6: a mono channel of the Combo XLR + 1/4" microphone input with no effects applied.
HeadRush Core can receive four separate audio signal channels from your computer. The channels are named and
routed as follows:
1: the left channel of your computer’s output audio signal, which will be sent directly out of HeadRush Core’s
main outputs and phones output.
2: the right channel of your computer’s output audio signal, which will be sent directly out of HeadRush Core’s
main outputs and phones output.
3: a mono channel of your computer’s audio signal, which will be sent back through HeadRush Core (see (4.16.3)
Reamping below).
4: not used in this scenario.
Important: Remember to set your DAW’s main outputs to be sent to 1/2.
54
(4.16.3) Reamping
Reamping is a process that adds the tone coloration of an amp to a pre-recorded audio signal—in this case, sending
audio from your DAW through HeadRush Core and then recording it back into your DAW. This is useful for saving
time because you can change the sound of an already-recorded guitar track without having to manually play the
same part again.
To use HeadRush Core to reamp an audio signal:
1. In your DAW, make sure HeadRush Core is selected as your audio interface for both recording/input and
playback/output.
2. Assign the output of the desired track to 3.
3. On HeadRush Core, tap the Menu icon in the upper-left corner of the Main screen, and then tap Global
Settings.
4. In the Global Settings screen, tap the USB Audio tab located in the column on the left side.
5. On the USB audio tab, set your sample rate to be the same sample rate as the one in your DAW.
6. Next, for the USB Mode setting, tap ReAmp.
7. Once the sample rate and mode settings are confirmed, set USB Audio to On.
8. In your DAW again, create a new audio track and assign its input. For a stereo input signal, select 1/2. For a
mono input signal, select 1.
9. Locate the point in your track where you want to start reamping.
10. On HeadRush Core, select the rig, blocks, or other parameters to achieve the sound you want.
11. In your DAW, start audio recording. The track you want to reamp will be sent through HeadRush Core and
recorded into the audio track you created earlier.

58
(4.19) Mic Dry Out
HeadRush Core’s Mic Dry Out feature enables you to still use a microphone while using rigs that use guitar-centric
signal paths (Straight Path, Middle Split, Immediate Split) that typically do not allow adding FX to the microphone
input.
This can be useful for different performance situations such as:
•
You require the full 14 blocks of your rig to attain a complex guitar sound, and while you do not need vocal
effects, you still need to sing simple backup vocals or talk to the audience between songs.
•
You are livestreaming a performance or taking online lessons using your HeadRush Core as an audio
interface and you still need a way to talk to your viewers or instructor.
To enable or bypass the Mic Dry Out signal on these types
of rigs, tap the Mic button located on bottom of the Main
screen next to the Tail and Signal Path buttons.
Although you are unable to add vocal effects to the microphone
signal to these types of rigs, the Mic Dry Out configuration
screen still enables you to enhance the Mic Dry Out signal with
a noise gate, compression, high pass filter, and simple EQ
settings.
To access the Mic Dry Out configuration screen to further
configure this signal, tap the Menu icon in the top left of
the Main screen, and then tap Mic Dry Out. On this screen,
you can adjust the following settings:
Preset: Select from included presets with preconfigured
settings for various uses.
Active: Enables or disables the Mic Dry Out feature.
Volume: Sets the level of the incoming Mic signal. You
can monitor the level using the meter above.
Gate Thresh: This is the volume level below which noise
gate will be applied. Any sound at this level or higher will
pass through the gate. Any sound lower than this level
will be reduced.
High Pass: Adjusts the center frequency of the high pass
filter applied to the mic signal.
Comp Threshold: This is the volume level at which compression is applied. Any sound at this level or higher
will be compressed. Any sound at this level or lower will bypass the compressor.
Comp Make-Up: Adds additional gain to the compressed signal.
EQ On: Enables or disables equalization. When enabled, you can adjust these additional settings:
EQ Low: Attenuate or boost the gain of the low frequency EQ band.
EQ Low Mid: Attenuate or boost the gain of the low-mid frequency EQ band.
EQ High-Mid: Attenuate or boost the gain of the high-mid frequency EQ band.
EQ High: Attenuate or boost the gain of the high frequency EQ band.
59
(4.20) Global EQ
The Global EQ screen lets you quickly apply additional equalization to all your rigs without permanently saving them.
These settings are especially useful when a venue, rehearsal space, or other environment has different acoustic
characteristics than the room where you originally created your rigs (e.g., the venue may sound “boomier,” or a
rehearsal space with soundproofing may deaden some of the high end).
To access the Global EQ screen, tap the Menu icon in the top left of the Main screen, and then tap
the Global EQ icon.
These settings determine if/how equalization is applied
the XLR outputs (the settings on the first tab in the left
column) and/or the 1/4” (6.35 mm) outputs (the settings
on the second tab in the left column half of the screen).
Each equalizer is a four-band parametric equalizer.
The available settings for each set of outputs are as
follows:
EQ: This setting determines whether equalization is
enabled (On) or disabled (Off) for the outputs.
Level: This setting determines if/how much the signal
level from the outputs is boosted or cut. This value
is applied to the level set by the Main knob.
Low, Low Mid, High & High Mid: The settings for each of these four frequency bands determine the shape of
the equalization:
The frequency setting (Hz) determines the center frequency of the low-frequency band, low-midfrequency band, high-frequency band, or high-mid-frequency band. You can adjust this by tapping on the
dot for the desired frequency band, and dragging it left or right. Alternatively, you can tap the frequency
field and use the Main knob to adjust it with more precision.
The gain setting (dB) determines how much the equalizer boosts or cuts the signal at the corresponding
frequency band. You can adjust this by tapping on the dot for the desired frequency band, and dragging it
up or down. Alternatively, you can tap the gain field and use the Main knob to adjust it with more precision.
The quality setting (Q) determines the width of the frequency band. The higher the setting, the wider the
band will be around the center frequency (the first setting). This setting is applied whether Low Band or
High Band is set to Shelf or Cut. You can adjust this by tapping and holding on the dot for the desired
frequency band and tapping and dragging left or right with a second finger. Alternatively, you can tap the
quality field and use the Main knob to adjust it with more precision.
The mode setting determines what type of equalization is applied to the lowest-frequency band (Low
Band) and to the highest-frequency band (High Band): Shelf or Cut. This setting is not available for the
Low Mid and High Mid bands. You can adjust this by tapping on the mode field and turning the Main
knob.
You can reset the Global EQ feature back to the factory defaults by tapping the Reset icon at the bottom of the
left column on this screen.
Note: This feature is specifically designed for adjusting the sound of every rig at once to accommodate your
performance environment. If you would like to use an EQ with a similar interface in a specific rig, try the Para EQ
block, located in the EQ category when adding a block to a rig.

Confirm Unsaved: This setting determines whether you will see a confirmation message if you change the rig while
there are unsaved changes on the current one. Tap On to enable these messages or Off to disable them.
Auto Assign Footswitches: This setting determines how models are assigned to the switches. Tap On if you want
models to be automatically assigned to the next available switch when you load them. Tap Off if you want models
to load without being assigned to a switch; you will have to assign them manually in the Hardware Assign screen.
Add Cab with Amp: This setting determines whether or not a specific cab and microphone are associated with the
amp when loaded. When this is set to Off, any cab and microphone used in the current rig will be completely
independent of the amp you select. When this is set to On, a specific cab and microphone combination will be
used if you change the amp’s Preset setting or if you load a new amp to the rig. You can change the cab and
microphone manually afterward by adjusting the parameters of the cab model.
Tempo LED: This setting determines whether the Tap Tempo footswitch’s LED blinks on the beat (Norm), on the
off beat (Inv), or whether the LED is turned off completely (Off).
Ext Amp Polarity: If it seems like your external amplifier is getting the opposite messages you intended, change
this parameter to invert the messages sent to the External Amp Footswitch Output. Select between Norm
(normal) and Inv (inverted).
Assign Looper Footswitch: This setting changes the hold function of footswitch 4. This can be assigned to the
Looper, Practice Tool, or Drum Machine.
Footswitch Function: This setting determines whether the footswitch action is triggered On Release or On Press of
the footswitch. When set to On Press, some footswitch functionality will be disabled via hold instead of press.
Remaining Storage: This meter shows how much storage space is available in HeadRush Core’s internal memory.

then delete the files from HeadRush Core using the File Browser or the USB Transfer feature.
61
Color Mod: If you have trouble distinguishing certain colors on your
HeadRush Core’s display, or if you just want to further customize
the color scheme, you can use the color mod parameters to adjust
their default settings.
If that sounds complicated to you, don’t worry! It is best to learn
simply by experimenting with the settings. While you experiment, a
sample of your adjustments will be shown in real time. See the
example below:
If you want to return to the default color scheme, the default
settings are as follows:
• Depth: 0%
• Color: 36 DEG
• Spread: 180 DEG
Note: The Color Mod feature is disabled when the Lock Screen feature is enabled.
(4.21.2) Audio
Guitar Input: This setting determines whether each rig’s input signal is taken from the guitar input (Guitar), or the
right (R) return input (FX Ret R). When set to Per Rig, the source is determined by the Rig Input setting of each
rig (see (4.4.2) Adjusting Settings > Parameters > In to learn about this). When set to FX Ret R or Per Rig, the
FX-Loop Stereo Return setting will be disabled; the signal will be mono.
Alt Guitar Source: This setting determines the point in the signal path from which the alternate output signal is
taken: Rig Input, Amp Input (the default setting), Amp Output, Cab Input, Cab Output, IR Input, IR 1024 In,
Amp 2 Input, Amp 2 Output, Cab 2 Input, Cab 2 Output, IR 2 Input, or IR 1024 2 In.
Mic +48V: This setting determines whether phantom power (+48V) is enabled (On) or disabled (Off) for the Combo
XLR+1/4” microphone input.
Important: Only enable phantom power if your microphone requires it. Most dynamic microphones and ribbon
microphones do not require phantom power, while most condenser microphones do. Consult your microphone's
documentation to find out whether it needs phantom power.

selected Sample Rate. Tap Off to disable the USB audio
signal. To change the Sample Rate, set USB Audio to Off
first, select the correct sample rate, set USB Audio to On
again, and restart your DAW.
Sample Rate: This setting determines the sample rate of the
USB audio signal: 44.1 kHz, 48.0 kHz, or 96.0 kHz. Remember
to select the same sample rate as the one in your DAW. Also,
set it before opening your DAW.
USB Mode: This setting determines what audio signal HeadRush Core sends over the USB connection and how
its outputs function while doing so:
• Live: The audio signal will be sent to your computer as well as to HeadRush Core’s outputs.
• DAW: The audio signal will be sent to your computer only. HeadRush Core’s outputs will be disabled to
prevent any latency while monitoring.
• Reamp: Your computer will send an audio signal to HeadRush Core, which will process it through the current
rig and send it back to your computer. HeadRush Core’s outputs will be disabled to prevent any latency while
monitoring. See (4.16.3) USB > Reamping to learn how to configure your DAW for this process.
USB In Level: This setting determines the incoming USB Audio level, from -60.0 dB to 12.0 dB.
(4.21.8) MIDI
These settings determine how HeadRush Core sends and
receives MIDI information to and from external devices. These
settings affect only HeadRush Core’s MIDI Input and MIDI
Output.
MIDI Thru: Tap On to use the MIDI Output as a MIDI
throughput; any MIDI information sent to HeadRush Core’s
MIDI Input will be sent directly to the MIDI Output. Tap Off
to use HeadRush Core’s MIDI output normally; HeadRush
Core will be able to send its own MIDI information out of
the MIDI output.
Receive MIDI Clock: Tap On to enable HeadRush Core to
receive MIDI clock information. Tap Off to use HeadRush
Core’s own internal MIDI clock (which will not be sent out).
Prog Change: Tap Send to enable or disable HeadRush
Core’s transmission of MIDI program change messages
when you load a rig. Tap Recv to enable or disable
HeadRush Core’s reception of MIDI program change
messages from an external MIDI device.
MIDI Channel: This setting determines the MIDI channel(s)
from which HeadRush Core will send and receive MIDI
messages. Tap this field, turn the encoder to select all
channels (Omni), or 1–16, and then press the encoder.
66
(4.21.9) Expression Pedal
The settings on this tab are for configuring an external expression pedal connected to HeadRush Core’s rear panel
EXPR and TOE inputs.
Toe Switch: Change this parameter to Latch if your external
expression pedal uses a latching toe switch, or Momnt if
your expression pedal uses a momentary toe switch.
Pedal Polarity: If it seems like your expression pedal is
registering motion in the wrong direction, you can change
this parameter to invert the pedal polarity. Select between
Norm (normal) and Inv (inverted).
“Intensity” on Drum Mach. Page: When set to ON, the
expression pedal will ignore any rig assignments and
instead automatically control the Intensity parameter when
the Drum Machine page is shown.
(4.21.10) Info
On this tab you can view HeadRush Core’s current firmware and hardware versions, and access HeadRush
Core’s License information.
Send anonymous usage statistics: This determines whether
or not your usage statistics will be sent occasionally to us,
enabling us to improve the HeadRush Core experience.
Reset All Global Settings: Tap Reset to reset all your global
settings to their factory defaults.
Reset Wi-Fi & Bluetooth Settings: Tap Reset to have
HeadRush Core forget all previously connected Bluetooth
devices and Wi-Fi networks.
67
(4.22) External MIDI Control
HeadRush Core can be controlled by incoming MIDI CC (control change) messages sent from external MIDI gear.
This external MIDI gear must be connected to the 5-pin MIDI Input or the USB-A connection. If USB-MIDI gear is
being connected to the USB-A port, it must be class compliant and require no software drivers to function.
The chart below lists the parameters that can be controlled by external MIDI gear:

While most of the parameters in the list above are actions that will be triggered when any CC data value (0-127) is
sent along with the correct CC#, some parameters require specific data values to function properly.
For example:
• When sending CC messages to control the Internal and External Expression Pedal (CC#1 and CC#2), you
can send an exact data value between 0-127 to make precise settings.
• When sending CC messages to control the Internal Footswitches (CC#49 through CC#53), you must send a
data value of 127 to simulate the press, and then another CC# message with a data value of 0 to simulate the
release of the footswitch. If you only send the press data value, the current assigned hold function to that
internal footswitch will be activated.
• When sending CC messages to control the Tap Tempo (CC#64), you must send the CC message multiple
times to simulate setting the Tap Tempo via an internal footswitch.
If your external MIDI device is not controlling the HeadRush Core as expected, try adjusting the CC data values like
the examples above, as well as exploring any settings that may be available on your MIDI device itself. Some MIDI
devices will have specific CC Toggle and CC Momentary modes where one mode may work better than the other.

Settings.
2. Select the Wi-Fi page on the left side of the screen, and ensure that the HeadRush Core Wi-Fi is set to On, and
then connect to your local network.
3. Select the HeadRush Remote page on the left side of the Global Settings screen, and ensure that the
HeadRush Remote setting is set to On.
4. On your computer, tablet, or other external device (connected to the same Wi-Fi network), open a web browser
and enter headrushcore.local or the IP address shown on HeadRush Core (for example, http://192.168.68.81)
into the address field.
