About the RP255  
Performance Mode  
When you first apply power to the RP255, it powers up in Performance mode. Performance mode  
provides access to all of the presets within the RP255 via the Up and Down Footswitches.  
Knob 1 selects a tone from theTone Library, Knob 2 selects an effect from the Effects Library,  
Knob 3 adjusts the Effects Level, and Knob 4 adjusts the Master Level (volume).  
Bypass Mode  
The RP255 presets can be bypassed via a true analog bypass circuit for a clean, unprocessed guitar  
signal. To bypass the RP255, press both Footswitches simultaneously. The Display reads Bypass  
indicating the preset is bypassed. Press either Footswitch to exit Bypass and return the RP255  
to the last preset used.  
Tuner Mode  
TheTuner in the RP255 allows you to quickly tune or check the tuning on your guitar. Enter  
Tuner mode by pressing and holding both Footswitches simultaneously. The Display briefly  
shows tunerindicating that you are inTuner mode. To begin tuning, play a note on your guitar  
(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 inTuner mode. The  
Expression Pedal controls the guitar volume while tuning. Exit tuner mode by pressing either  
Footswitch.

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 Compressor, Distortion, Amp/Cabinet model,  
and EQ 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/Creating Presets on page 16). Changing between  
differentTone Library defaults does not change the Chorus/FX, Delay or Reverb, letting you ex-  
periment 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 16). Changing between different Effects Library defaults does not  
change the Compressor, Distortion, Amp/Cabinet model, and EQ 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.  
Master Level (Knob 4)  
This knob controls the overall output volume of all of the RP255 (Presets, Drum Machine, and  
USB playback).  
X-EditTM Editor/Librarian  
You can edit your RP255 with your computer, using the X-EditTM Editor/Librarian. Download X-  
EditTM, USB drivers, and documentation from www.digitech.com. Open the readme file for detailed  
instructions about installing and using this software.

Presets  
Presets are named and numbered locations of programmed sounds which reside in the RP255.  
Presets are recalled with the Footswitches. The active effects in each preset are indicated by  
lighted LEDs in the Effect Matrix. The RP255 comes with 60 User presets (1-60) and 60 Fac-  
tory presets (61-120). 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 60 User  
presets are exact duplicates of the 60 Factory presets. This allows you to create your own presets  
without losing the sounds that came with the RP255.  
TheTone Library knob, Effects Library knob, and Effects Level knob make it easy to  
quickly load preset tones, effects, and effects chains.  
1. Select a tone  
with the  
Tone Library knob

SectionTwo - Editing Functions  
Editing/Creating Presets  
The RP255 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 47) based on different musical styles. The Effects Library knob will then let you select  
from a palette of effects chains (see page 48), from simple delays to full multi-effect signals with  
modulation, delay and reverb. Use the Effects Level Knob to easily increase or decrease the  
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.  
To edit and create a preset:  
1. Use the Footswitches to select the preset you wish to edit.  
2. 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.  
3. Press the Edit Up/Down buttons to begin selecting the individual Effects rows to edit their  
parameters.  
4. To bypass or enable an Effect row, press the Tone Library knob.  
5. Use Knobs 2-4 to modify the effects’ parameter settings.  
6. Select the Pickup row and use Knob 4 to adjust the Preset Level.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
16  
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 RP255 will revert to the stored values for the preset.  
Storing/Copying/Naming a Preset  
Once the preset has been modified to your liking, you may store your settings to any of the  
60 User preset locations (presets 1-60). 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 Dis-  
play 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 sec-  
ond stage of the storing process. The Display begins to flash.

4. Select the User preset location where your new sound will reside using the Up and Down  
Footswitches. The display alternates between showing the preset name and User preset num-  
ber 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.

SectionThree - Models and Parameters  
About the Models  
The RP255 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 RP255 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 RP255 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  
RP255’s effects outlines what each effect and parameter does.  
Pickup  
The Pickup Simulator provides the thick tone of a humbucker pickup to a guitar with single coil  
pickups, or the bright, edgy sound of a single coil pickup to a guitar with a humbucker. This gives  
you the best of both worlds without having to change guitars during a performance.  
Pickup Model - Knob 1 selects the Pickup model to be simulated. Values include: SC>Hb  
(gives a single coil pickup the warm tone of a humbucker), and Hb>SC(gives a humbucker  
the unique sound of a single coil). Press this knob to turn Pickup modeling on and off.  
Preset Level - Knob 4 adjusts the preset’s level.  
Wah  
Wah is an effect controlled by an Expression Pedal making the guitar sound as if it’s saying “Wah.”  
Wah Model - Knob 1 selects the Wah model. Values include: FuLrnG(DigiTech® Full  
Range Wah sweeps the entire spectrum of audible frequencies), CrYwah(Cry Wah is a tra-  
ditional sounding Wah), and clyde(based on aVox® Clyde McCoyTM Wah). Press this knob  
to turn Wah models on and off.  
Wah Minimum - Knob 2 adjusts the Wah Pedal Minimum. Ranges from 0(toe up) to 99  
(toe down).  
Wah Maximum - Knob 3 adjusts the Wah Pedal Maximum. Ranges from 0(toe up) to  
99(toe down).

Chorus/FX  
The Chorus/FX row in the RP255 is a multi-function module, allowing you to select Effect models  
such as Chorus, Flanger, Phaser, Tremolo, Panner, Vibrato, Rotary Speaker, YaYa™, AutoYa™,  
SynthTalk™, Envelope Filter (auto wah), Detune, Pitch Shift, andWhammy™ 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 2-4 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 RP255 includes the  
following Chorus Effect models: Ce CHS(based on the classic Boss® CE-2 Chorus), CHOruS  
(DigiTech®’s Dual Chorus), and MCHOrS(DigiTech’s famous Multi Chorus®).

27  
Waveform (X-EditTM only for DigiTech Chorus models) - Selects a waveform:  
triang, Sine, or Square.  
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 RP255 includes the following Flanger Effect models: fLangr (the DigiTech  
Flanger), and mxFLgr (based on an MXR® Flanger).  
Knobs 2, 3, and 4 have the following functions for the Flanger models:

Phaser (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, differ-  
ent frequencies get canceled resulting in a warm sort of twisting sound.  
Knobs 2, 3, and 4 have the following functions for the two Phaser models:  
Speed - Knob 2 adjusts the rate (Speed) of the modulation. Ranges from 0to 99.

Speed - Knob 2 adjusts the rate (Speed) at which the pitch modulates. Ranges from 0to  
99.  
Depth - Knob 3 adjusts the intensity (Depth) of the modulating pitch. Ranges from 0to  
99.  
Rotary Speaker (rOtArY)  
Rotary Speaker is an emulation of 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.  
Speed- Knob 2 adjusts the rate (Speed) of the spinning speakers. Ranges from 0to 99.  
Intensity - Knob 3 controls the intensity of the effect. Ranges from 0to 99.

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.TheVibroPan also incorporates an automatic panner  
with the vibrato effect that creates a lush chorus-like sound.  
Speed - Knob 2 adjusts how fast the signal is being modulated.  
Depth - Knob 3 adjusts the amount of pitch change.  
Vibrato/Pan- Knob 4 adjusts the amount of panning incorporated with the vibrato effect.  
When the “Vib” control is at “0”, this effect is a standard vibrato. As the Level parameter is  
turned up, the phase difference of the vibrato signal sent to the two channels is changed until  
a full stereo image is obtained at “99”.  
Waveform (X-EditTM only) - Selects a waveform: triang, Sine, or Square.  
Tremolo (trMoLO)  
ATremolo effect modulates the volume of the signal at an even rate.  
Speed - Knob 2 adjusts the rate (Speed) at which the volume modulates. Ranges from 0to  
99.  
Depth - Knob 3 adjusts the intensity (Depth) of the modulating volume. Ranges from 0to  
99.  
Waveform - Knob 4 selects a waveform: triang, Sine, or Square.  
Panner (PAnner)  
An Auto Panner modulates the sound from left to right at an even rate.  
Speed - Knob 2 adjusts the rate (Speed) at which the signal pans from side to side. Ranges  
from 0to 99.

Intensity - Knob 3 controls the intensity of the Wah effect. Ranges from 0to 99.  
DigiTech Whammy™ (wHammy)  
The DigiTechWhammyTM is an effect that uses an Expression Pedal to bend the pitch of the in-  
coming signal, or add a bendable harmony with the original signal. As the Pedal is moved, the note  
bends either up or down. When DigiTechWhammy is selected, it is automatically placed before  
the Amp modeling as shown in the block diagram on page 19.

list of parameters that can be linked to the Expression Pedal.  
3. Rotate Knob 3 to select the minimum (heel) value the assigned parameter will reach with the  
Expression Pedal in the toe up position.  
4. Rotate Knob 4 to select the maximum (toe) value the assigned parameter will reach with the  
Expression Pedal in the toe down position.

Factory Reset  
This function resets the RP255 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 RP255.  
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 rStOrDappears in the display and  
release (The Factory Reset procedure takes approximately 20 seconds). The Expression Pedal  
calibration procedure now commences.

Expression Pedal Calibration  
The Expression Pedal on the RP255 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 both 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 PDLCALappears in the display (BYPASS  
and tunerwill be displayed before PDLCALis accessed)  
2. When the Display prompts you with tOe Dn, rock the Expression Pedal forward (toe down)  
and press either Footswitch.  
3. When the Display prompts you with tOe uP, rock the Expression Pedal back (toe up) and  
press either Footswitch.  
4. The Display now prompts you to calibrate theV-Switch sensitivity (VSwxxx), where XXXis the  
currentV-Switch threshold. Rock the Expression Pedal forward and press firmly on the toe  
once to turn theV-Switch on (wah On), and again to turn theV-Switch off (wahOFF).  
5. If theV-Switch is too sensitive, press the right Up Footswitch to raise the threshold (range is  
0-200). Keep testing theV-Switch sensitivity and adjust the threshold until it only engages when  
you want it to (too sensitive a setting will lead to theV-Switch falsely triggering on or off when  
using the Expression Pedal).  
6. When theV-Switch sensitivity is set to your satisfaction, press both Up/Down Footswitches  
simultaneously to exit.  
Note: If the Display shows errOr, an error has occurred and steps 2 through 5 should  
be repeated.
