About the BP355

Performance Mode

When you first apply power to the BP355, it powers up in Performance mode. Performance
mode provides access to all of the presets within the BP355 via the Up and Down Foot-
switches. The Amp A/B Footswitch toggles between two amp channels for the selected
preset. Knob 1 selects a tone from the Tone Library, Knob 2 selects an effects chain from the
Effects Library, Knob 3 adjusts the Effects Level, and Knob 4 adjusts the Amp Gain, Knob 5
adjusts the Amp Level, and Knob 6 adjusts the Master Level (volume).

Stompbox Footswitch Mode

The BP355 includes a very convenient Stompbox Footswitch mode, where the Up, Down, and
Amp A-B footswitches function as on/off switches for the Distortion, Chorus/FX and Delay
effects. To enable Stompbox Footswitch mode, press the Up and Amp A/B Footswitches
simultaneously. The Display will read STOMP briefly indicating Stompbox footswitch mode has
been enabled. The Down, Up, and Amp A/B Footswitches will now turn Distortion, Chorus/
FX, and Delay effects respectively on and off in the current preset. Note: While Stompbox
footswitch mode is active, you cannot navigate through the BP355’s presets, nor can you change
the Amp A/B channels in the current preset.

To exit Stompbox footswitch mode and return to Preset footswitch mode, press the Up and
Amp A/B Footswitches simultaneously again. The Display will read PRESET briefly indicating
Preset footswitch mode is now active again.

1

Bypass Mode

The BP355 presets can be bypassed via an analog bypass circuit for a clean, unprocessed bass sig­nal. To bypass the BP355, press the Up and Down Footswitches simultaneously. The Display
reads Bypass indicating the preset is bypassed. Press any footswitch to exit Bypass and return
the BP355 to the last preset used.

Tuner Mode

The Tuner in the BP355 allows you to quickly tune or check the tuning on your bass. Enter Tuner
mode by pressing and holding the Up and Down Footswitches simultaneously for 2 seconds.
The Display briefly shows TUNER indicating that you are in Tuner mode. To begin tuning, play
a note on your bass (a harmonic at the 12th fret usually works best). The Display shows the
note being played. The Matrix LEDs indicate whether you are sharp or flat. The top 5 red LEDs
indicate the note is sharp and should be tuned down. The bottom 5 red LEDs indicate the note
is flat and should be tuned up. The center green LED indicates the note is in tune. The output is
muted in Tuner mode. The Expression Pedal controls the bass volume while tuning. Exit tuner
mode by pressing any Footswitch.

In Tuner mode, you can change your tuning reference. The default factory setting is A=440 Hz
(displayed as A=440). Rotating Knob 1 selects alternate dropped tunings and tuning references.
Alternate tunings are A = A, A = G, A = G
window briefly flashes the current tuning reference.

The display

Tone Library (Knob 1)

In Performance mode, this knob selects a variety of genre-based amp tone defaults ranging from
Blues to Metal to Country. Behind the scenes, the Fretless/Wah, Compressor, Distortion, Amp/
Cabinet model, EQ, and Noise Gate are configured to create a specified tone with a single
click of this knob. You can further refine the sound by editing the preset (see Editing/Creat-
ing Presets on page 11). Changing between different Tone Library defaults does not change
the Chorus/FX, Delay or Reverb, letting you experiment with different amp styles quickly in the
context of the current effect chain.

Effects Library (Knob 2)

In Performance mode, this knob selects a variety of post-amplifier model effect chains (Chorus,
Chorus + Delay, Delay + Reverb, etc.). You can further refine the sound by editing the preset
(see Editing/Creating Presets on page 11). Changing between different Effects Library defaults
does not change the Fretless/Wah, Compressor, Distortion, Amp/Cabinet model, EQ, and Noise
Gate settings, letting you experiment with different effect chains quickly in the context of the
current amp tone.

Effects Level (Knob 3)

In Performance mode, this knob changes the relative level of the post-amp effects (Chorus/FX,
Delay, and Reverb). This can be thought of as an effects mix control, where turning this knob
clockwise increases the level of these effects and turning it counter-clockwise decreases the
level of these effects.

Amp Gain (Knob 4)

This knob adjusts the Gain (distortion) for the selected Amp model (not available for Direct).

Amp Level (Knob 5)

This knob adjusts the Level (volume) of the selected Amp model.

2

Master Level (Knob 6)

This knob controls the overall output volume of all of the BP355’s presets.

X-EditTM Editor/Librarian

You can edit your BP355 with your computer, using the X-EditTM Editor/Librarian. Download X­EditTM, USB drivers, and documentation from www.digitech.com.

Presets

Presets are named and numbered locations of programmed sounds which reside in the BP355.
Presets are recalled with the Footswitches. The active effects in each preset are indicated by
lighted LEDs in the Effect Matrix. The BP355 comes with 70 User presets (1-70) and 70 Factory
presets (F1-F70). The User presets are locations where your creations may be stored. The
Factory presets do not allow you to store any changes to them. From the factory, the 70 User
presets are exact duplicates of the 70 Factory presets. This allows you to create your own
presets without losing the sounds that came with the BP355.

Applying Power

Before applying power to anything, set your amp(s) to a clean tone and set the tone controls to
a flat EQ response (on most amps, this would be 0 or 5 on the tone controls). Then follow the
steps listed below.

1. Turn the amp volume all the way down.

2. Connect the plug of the PS0913B power supply to the power jack on the rear panel of the
BP355.

3. Connect the other end of the PS0913B power supply to an AC outlet. Turn the BP355’s
Master Level knob (Knob 6) down to “0”.

4. Turn the power of your amplifier(s) to the on position and adjust the volume(s) to a normal
playing level.

5. Gradually increase the BP355’s Master Level knob to achieve the desired volume.

2. Connect PS0913B to power jack

4. Turn amp volume up

3. Connect PS0913B
to AC outlet and
turn the BP355’s
Master Level to “0”

1. Turn amp volume down

5. Turn the BP355’s Master Level
to the desired listening volume

Section Three - Editing Functions

Editing/Creating Presets

The BP355 is designed to make preset editing and creation easy and intuitive. When creating
your own sound, you must first start with an existing preset. Note that the preset you begin
with doesn’t have to be in the memory location you intend to have it reside, since you can
store it to any User preset location during the store procedure.

The easiest way to start is by using the Tone Library and Effects Library knobs. The Tone
Library knob will let you select from a variety of pre-programmed amp/distortion tones (see
page 33) based on different musical styles. The Effects Library knob will then let you select
from a palette of effects chains (see page 33), from simple delays to full multi-effect signals with
modulation, delay and reverb. Use the Effects Level Knob to increase or decrease the overall
Chorus/FX, Delay and Reverb levels if desired. Using these three controls should get you close
to a sound you are after. From there you can then use the Edit buttons to navigate through
the individual effects for some fine tune edits.

1. Select a tone
with the

Tone Library knob

To edit and create a preset:

1. Use the Up and Down Footswitches to select the preset you wish to edit.

2. If you find a preset close to what you want, you can begin editing the effect parameters by

pressing the Edit Up/Down buttons and selecting the Effect row you want to edit.

3. If you are trying to find something different from the existing presets, begin by using the

Tone Library, Effects Library and Effects Level knobs to get close to a sound you want.

4. Press the Edit Up/Down buttons to begin selecting the individual Effects rows to edit their

parameters.

5. To bypass or enable an Effect row, press the Tone Library knob.

6. Use the Knobs 2-6 to modify the effects’ parameter settings.

7. When editing the Amp Model and EQ rows, use the Amp A/B Footswitch to select be-

tween the two amp channels. You can then edit each channel’s Amp Model, Cabinet Model,
Amp Gain, Amp Level, and EQ settings independently.

8. Select the Fretless/Wah row using the Edit Up/Down buttons and use Knob 6 to set the

overall Preset Level.

Note: Anytime a stored value within a preset is changed, the Store button LED lights up. This
indicates that you need to store the changes. Changing presets, or turning the power off before
storing any changes, erases any changes made and the BP355 will revert to the stored values for
the preset.

2. Select an effect

or effects chain with the

Effects Library knob

3. Adjust the

effects level with the

Effects Level knob

11

Storing/Copying/Naming a Preset

Once the preset has been modified to your liking, you may store your settings to any of the
70 User preset locations (presets 1-70). The following steps outline the procedure for storing
changes to a preset or copying a preset to a different location:

1. Press the Store button once. The Store button LED blinks and the first character in the

Display flashes, indicating that you can now name your custom creation.

2. Use Knob 1 to select the alpha-numeric character and Knob 2 to select the next character

location.

1. Press Store;
characters in Display
flash individually

2. Use Knobs to
name Preset

3. Once the desired name is shown in the display, press the Store button again to enter the

second stage of the storing process. The red Display begins to flash.

4. Select the User preset location where your new sound will reside using the Up and Down
Footswitches. The displays show the preset name and User preset number about to be

overwritten.

3. Press Store again;
Preset number flashes

4. Select destination
with Footswitches

5. Press the Store button again to save the changes.

The procedure for copying one preset to another preset location is the same. Use the Foot-
switches to select the preset that you want to copy, then follow steps 1-4 for storing a preset
as described above. Press either Edit button at any time to abort the Store procedure.

Section Four - Models and Parameters

About the Models

The BP355 can be thought of as several different “virtual” amplifiers and individual, high-tech
stompboxes in a single programmable package. With stompboxes, the order in which they are
connected affects the overall sound. The BP355 has placed the Amp and Effect models in an
order for optimum results. The following diagram shows the order in which they are connected.

Model Definitions

Each Amp and Effect model within the BP355 can be programmed to suit your personal taste
and application. Understanding how these components alter the sound, and how each parame­ter alters the effect, will help you achieve the sound you are looking for. The following overview
of the BP355’s effects outlines what each effect and parameter does.

Fretless/Wah

The Fretless simulator creates a fretless bass sound when using a fretted bass. Wah is an effect
controlled by an Expression Pedal making the bass sound as if it’s saying “Wah.”

Fretless/Wah Model - Knob 1 selects the Fretless Simulator or Wah model.

FRET 1 - 3 (Fretless Simulator), CRYwah (based on a Dunlop
clyde(based on a Vox® Clyde McCoyTM Wah), and FULRNG (DigiTech® Full Range Wah

sweeps the entire spectrum of audible frequencies). Press this knob to turn the model on
and off.

Fretless Amount - Knob 2 adjusts the amount of Fretless Simulator mixed in with the
dry signal. Ranges from 0 to 99.

Wah Minimum - Knob 3 adjusts the Wah Pedal Minimum. Ranges from 0 (toe up) to
99 (toe down).

®

Cry Baby Wah®),

Wah Maximum - Knob 4 adjusts the Wah Pedal Maximum. Ranges from 0 (toe up) to
99 (toe down).

Wah Level - Knob 5 adjusts the Wah Level. Ranges from 0dB to +12dB.

Note: If any of the 3 Wah types are selected in Fretless/Wah, the wah can be turned on and off

by pressing firmly on the Expression pedal toe. The Expression pedal will override any expres­sion link and control the wah when it is enabled. If any of the 3 Fretless types are selected, Wah
cannot be used and pressing on the Expression pedal toe will do nothing.

13

Compressor

A Compressor is used to increase sustain, tighten up the bass, and prevent the signal from clip­ping the input of other effects. It sets a maximum boundary for the strength of a signal.

®

Comp Model - Knob 1 selects one of three Compressor models: DIGCMP (DigiTech
Compressor), CSCOMP (Based on a Boss

®

CS-2 Compressor/Sustainer), or DYNCOMP

(Based on an MXR® Dynacomp). Press this knob to turn the selected Compressor model
on and off.

EQ

The BP355’s EQ helps further shape your tone with Bass, Midrange, and Treble controls. To help
get you started, there are four preset EQ curves: Mid Boost (midbst), Scoop (ScooP), Bright
(BRight), and Warm (WarM) that can be selected using Knob 1. Bass, Midrange, and Treble
parameters range from -12dB to +12dB.

Note: You can modify EQ settings for each amp channel (Amp A and Amp B). When the EQ
row is selected, press the Amp A/B Footswitch to select a channel. The display will show
which channel is selected (Amp A or Amp B).

EQ Model - Knob 1 selects between 4 different EQ modes (Mid Boost, Scoop, Bright,
and Warm), each with different frequency centers for Mid and Treble. Pressing this knob
turns the EQ on and off.

Bass - Knob 2 adjusts the amount of low end level (Bass). Ranges from -12dB to 12dB.

Mid Frequency - Knob 3 selects the frequency that the Mid parameter adjusts. Ranges

from 300 Hz to 5000 Hz.

from -12dB to 12dB.

Treble Frequency (X-Edit

TM

only) - This parameter selects the frequency that the Treble

parameter adjusts. Ranges from 500 Hz to 8000 Hz.

Noise Gate/Auto Swell

A Noise Gate is designed to eliminate noise while you are not playing, or provide an auto
volume swell effect.

Gate Model - Knob 1 selects between the DigiTech

®

noise gate or the volume swell

effect. Values include: gate (Selects the Noise Gate) and swEll (Selects the Auto Swell
effect.) Press this knob to turn the Noise Gate/Auto Swell on and off.

Threshold (Noise Gate only) - Knob 2 sets the signal strength (Threshold) required to
open or close the Noise Gate. Parameters range from 0 (opens easily) to 99 (requiring
strong signals to open).

Attack Time - Knob 3 sets the attack time. Ranges from 0 (shorter attack time) to 99
(longer attack time).

Chorus/FX

The Chorus/FX row in the BP355 is a multi-function module, allowing you to select Effect
models such as Chorus, Flanger, Phaser, Vibrato, Rotary Speaker, Tremolo, Panner, Envelope
Filter (auto wah), AutoYa™, YaYa™, SynthTalk™, Step Filter, Whammy™, Pitch Shift, Detune,
Harmony, and Octaver effects. When the Chorus/FX row is selected, Knob 1 is used to choose
the Effect model. Press this knob to turn these Effect models on and off. Only one of the effects
in this row can be used at a time. After selecting the type of effect in this module, Knobs 2-6
can then be used to adjust the individual parameters associated with the selected effect. The
following list describes each Effect model and its parameters in more detail:

Chorus

A Chorus adds a short delay to your signal. The delayed signal is modulated in and out of tune
and then mixed back with the original signal to create a thicker sound. The BP355 includes the
following Chorus Effect models: CE CHS (based on the classic Boss
(based on the TC Electronic Chorus), CHORUS (DigiTech
Tech’s famous Multi Chorus

®

).

®

’s Dual Chorus), and MCHORS (Digi-

Flanger

A Flanger uses the same principle as a Chorus but uses a shorter delay time and adds regenera­tion (or repeats) to the modulating delay. This results in an exaggerated up and down sweeping
motion to the effect. The BP355 includes the following Flanger Effect models: fLangr (the
DigiTech
Flanger), and ehFLgr (based on an Electro-Harmonix

®

Flanger), trgfLG (the DigiTech Triggered Flanger), mxFLgr (based on an MXR®

Phaser

A phaser splits the incoming signal, and then changes the phasing of the signal. This signal is then
taken in and out of phase and mixed back in with the original signal. As the phasing changes, dif­ferent frequencies get canceled resulting in a warm sort of twisting sound. The BP355 includes
the following Phaser models: phaser (the DigiTech Phaser), tphase (the DigiTech Triggered
Phaser), mxphas (based on an MXR Phase 100), and ehphas (based on an Electro-Harmonix
Small Stone).

Vibrato (viBRaT)

The DigiTech Vibrato effect modulates the pitch of the incoming signal at an even rate.

Pre/Post Amp - Knob 2 determines where the effect appears in the effects chain. Turn
counter-clockwise for Pre (appears before the Distortion effect), or clockwise for Post
(appears after the Noise Gate effect).

Speed - Knob 3 adjusts the rate (Speed) at which the pitch modulates. Ranges from 0 to

99.

Depth - Knob 4 adjusts the intensity (Depth) of the modulating pitch. Ranges from 0 to

99.

Rotary Speaker (ROTARY)
The Rotary Speaker emulates a device that included a spinning horn and woofer. The rotation of
these two speakers produced an interesting combination of the sound panning from side to side.
This produced a slight pitch change due to the speed of the sound coming towards, and then
going away from the listener.

Pre/Post Amp - Knob 2 determines where the effect appears in the effects chain. Turn
counter-clockwise for Pre (appears before the Distortion effect), or clockwise for Post
(appears after the Noise Gate effect).

Speed - Knob 3 adjusts the rate (Speed) of the spinning speakers. Ranges from 0 to 99.

Intensity - Knob 4 controls the intensity of the effect. Ranges from 0 to 99.

Doppler - Knob 5 controls the Pitch Shift effect that is the ratio between the horn and

the rotor positions. Ranges from 0 to 99.

X-Over - Knob 6 sets the crossover frequency between the rotor and the horn. Ranges
from 0 to 99.

19

VibroPan (vibpan)

A vibrato is an effect that modulates the pitch of the incoming signal. This will take the whole
signal slightly in and out of tune at a steady pace. The DigiTech® VibroPan also incorporates an
automatic panner with the vibrato effect that creates a lush chorus-like sound.

Pre/Post Amp - Knob 2 determines where the effect appears in the effects chain. Turn
counter-clockwise for Pre (appears before the Distortion effect), or clockwise for Post
(appears after the Noise Gate effect).

Speed - Knob 3 adjusts how fast the signal is being modulated.

Depth - Knob 4 adjusts the amount of pitch change.

Phrase Looper

The BP355 features a built-in 20 second Phrase Looper for creating on the fly performance
loops of the music you play. The Phrase Looper can be accessed any time during performance
and used with any of the BP355’s presets.

To use the Phrase Looper, follow these steps:

1. Press and hold the Amp A/B Footswitch for 2 seconds until LOOPER appears in the dis-

play. The Looper LED in the matrix will also light indicating the Looper is now active.

2. Arm the Phrase Looper to record by pressing the Amp A/B Footswitch again. The display

will read ARMED meaning it is ready for you to start playing (You can also start recording
immediately when this footswitch is pressed).

3. Begin playing a phrase on the bass. The Phrase Looper will begin recording anything that is

played. The display will read RECoRD.

4. Once you are ready to set the loop point, press any footswitch. The display will briefly read

PLAY and the recorded phrase will now begin playing back.

5. To add an overdub to the looped phrase, press and hold the Amp A/B Footswitch. The

display will read OVRDUB. While holding the footswitch, begin playing the overdub phrase to
be added to the loop. When the Amp A/B Footswitch is released, the display will briefly
flash PLAY and the looped phrase will continue with the newly added overdub phrase added.

6. To stop the Phrase Looper, press and release the Amp A/B Footswitch quickly. You can

resume playback by pressing this footswitch again.

7. To clear a recorded loop, stop the loop playback first as outlined in step 6 and then press and

hold the Amp A/B Footswitch for 2 seconds until the display read CLEARD.

To exit the Phrase Looper mode, press and hold left Amp A/B Footswitch for 4 seconds until
the display reads LPEXIT. Exiting the Looper clears the recorded loop.

While the Phrase Looper is active, the Amp A/B Footswitch cannot be used to select the amp
A/B channels in the BP355’s presets. The preset Up and Down Footswitches can still be used
navigate through all of the BP355’s presets.

Note: While the Phrase Looper feature is active, the Drum Machine feature is not available.

Drum Machine

The BP355 includes a built-in drum machine loaded with 60 useful patterns and 5 metronome
settings that are easily accessible at the touch of a button (the Drums button, specifically).
Pressing the Drums button will enable the drum machine and start playback of the selected
drum pattern (except when in Store or Bypass mode). When you turn the drum machine on,
the display reads Drums ON; when you turn the drum machine off, the display reads Drums
Of.

When the Drums row is selected (using the Edit buttons), Knob 1 selects the drum Style,
Knob 2 adjusts the drum Pattern, Knob 3 adjusts the Tempo of the drum pattern and Knob 4
adjusts the drum machine playback level. Press the Drums button again to stop playback of the
drum loop.

Aux Input

The Aux Input allows you to connect an MP3 or CD player to the BP355 and jam with your
favorite artists. The signal from your MP3 or CD player is output through the left, right, and
headphone outputs of the BP355. To use the Aux Input, connect the headphone output of your
MP3 or CD player to the Aux Input on the rear panel of the BP355 using an 1/8" stereo cable,
and press play on your MP3 or CD player. Use the playing device’s volume control and the
BP355’s Master Level knob to balance the levels.

Expression Pedal

The Expression Pedal on the BP355 can be linked to control the BP355’s Volume, Wah, Wham­my™, YaYa™, or almost any of the BP355’s other parameters in real time with your foot. When
a parameter has been linked to the Expression Pedal, a minimum (heel) and maximum (toe)
value can also be specified. Apply extra pressure to the toe of the Expression Pedal to activate
the V-switch, and the Expression Pedal switches between the linked parameter and the Wah. The
procedure for linking a parameter to the Expression Pedal is as follows:

1. Press either Edit button until the Expression row has been selected (indicated by the LED

lighting on the Expression row).

2. Rotate Knob 1 until EXPPDL appears in the Display.

3. Rotate Knob 2 until the desired parameter to be linked appears in the Display. See page 32

for a complete list of parameters that can be linked to the Expression Pedal.

4. Rotate Knob 3 to select the minimum (heel) value the assigned parameter will reach with

the Expression Pedal in the toe up position.

5. Rotate Knob 4 to select the maximum (toe) value the assigned parameter will reach with

the Expression Pedal in the toe down position.

6. Store your Expression Pedal assignment to your preset. See page 12 for more information on
the storing procedure.

LFOs

The BP355 includes two assignable low frequency oscillators (LFO 1 and LFO 2) which
can be assigned to any of the same parameters available for assignment to the Expression
Pedal. A low frequency oscillator will automatically vary the value of the assigned parameter at
a steady rate. A minimum and maximum value each LFO will reach may be also be assigned.
For instance, if the Amp Gain was assigned to LFO 1, and the minimum value was set at 1 and
the maximum value was set at 99, the BP355 would automatically sweep the amount of

28

distortion from a clean sound to a distorted sound. Individual LFO speeds are also available
for assignment. In the previous example, the LFO speed would determine the length of time it
took the LFO to sweep from the clean to the distorted sound. The procedure for assigning the
LFOs in the BP355 is as follows:

1. Press the Edit button until the Expression row has been selected (indicated by the LED
lighting on the Expression row).

2. Rotate Knob 1 to select one of the two LFO links, LFO 1 (LFO1) or LFO 2 (LFO2) .

3. Rotate Knob 2 to select the parameter you want linked to the LFO 1 or LFO 2. See page
32 for a list of assignable parameters.

4. Rotate Knob 5 to select which waveform you want the LFO to use, Triangle (TRIanG), Sine
(SINE), or Square (SQUARE).

5. Rotate Knob 6 to select the speed you want the parameter to be controlled at.

Factory Reset

This function resets the BP355 to its original factory settings. This procedure erases all custom
User presets, and recalibrates the Expression Pedal.

ATTENTION: Performing this function will erase all user-programmed
data. All such data will be lost forever! Be sure you want to erase the
memory and start fresh before continuing with this procedure.

The procedure for performing a Factory Reset is as follows:

1. Press and hold the Store button while powering up the BP355.

2. When the display prompts you with FACRST, release the Store button, which is now flashing.

3. Press and hold the flashing Store button for 3 seconds until RSTORD appears in the display
and release. The Restore procedure takes several seconds to complete; during the proce­dure, the display will count up. After the Restore procedure is complete, the Expression
Pedal calibration procedure will begin. See step two of the Expression Pedal Calibration sec­tion below.

Expression Pedal Calibration

The Expression Pedal on the BP355 needs to be recalibrated for use after a factory reset has
been performed. This calibration procedure is automatically entered after a factory reset proce­dure. (You can also initiate the calibration procedure by pressing and holding the Up and Down
Footswitches for approximately 5 seconds.) In the event the Pedal’s calibration fails, or if the
Pedal does not function properly, it can be re-calibrated using the Pedal Calibration procedure.
This will not erase the User presets. The procedure for Calibrating the Expression Pedal is as
follows:

1. Press and hold the Up/Down Footswitches until PDLCAL appears in the display (BYPASS,
TUNER, and Exit will be displayed before PDLCAL is accessed, after about 5 seconds.)

2. When the Display prompts you with TOE DN, rock the Expression Pedal forward (toe
down) and press either the Up or Down Footswitch.

3. When the Display prompts you with TOE UP, rock the Expression Pedal back (toe up)
and press either the Up or Down Footswitch.

4. The Display now prompts you to calibrate the V-Switch sensitivity (VSwxxx), where XXX is
the current V-Switch threshold. Rock the Expression Pedal forward and press firmly on
the toe once to turn the V-Switch on (wah ON), and again to turn the V-Switch off
(wahOFF).

29

5. If the V-Switch is too sensitive, press the right Up Footswitch to raise the threshold (range
is 0-200). Keep testing the V-Switch sensitivity and adjust the threshold until it only engages
when you want it to (too sensitive a setting will lead to the V-Switch falsely triggering on or
off when using the Expression Pedal).

6. When the V-Switch sensitivity is set to your satisfaction, press both Up/Down Footswitch-

es simultaneously to exit.

Note: If the Display shows ERROR, an error has occurred and steps 2 through 5 should be

repeated.
