About the RP350
Performance Mode
When you first apply power to the RP350, it powers up in Performance mode. Performance
mode provides access to all of the presets within the RP350 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).
Bypass Mode
The RP350 presets can be bypassed via a true analog bypass circuit for a clean, unprocessed
guitar signal. To bypass the RP350, press the Up and Down Footswitches simultaneously. The
Display reads  indicating the preset is bypassed. Press either the Up or Down Foot-
switch to exit Bypass and return the RP350 to the last preset used.
Tuner Mode
The Tuner in the RP350 allows you to quickly tune or check the tuning on your guitar. Enter
Tuner mode by pressing and holding the Up and Down Footswitches simultaneously for 2
seconds. The Display briefly shows  indicating that you are in Tuner 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 in Tuner mode. The Expression Pedal controls the guitar 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 ). Rotating Knob 1 selects alternate dropped tunings and tuning references.
Alternate tunings are A = A, A = G, A = G, and tuning references A=427 - A=453. The display
window briefly flashes the current tuning reference.
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, 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/Creating 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 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 Acoustic).
Amp Level (Knob 5)
This knob adjusts the Level (volume) of the selected Amp model.
Master Level (Knob 6)
This knob controls the overall output volume of all of the RP350’s presets.
X-EditTM Editor/Librarian
You can edit your RP350 with your computer, using the X-EditTM Editor/Librarian. Download X-
EditTM, USB drivers, and documentation from www.digitech.com.
Presets
Presets are named and numbered locations of programmed sounds which reside in the RP350.
Presets are recalled with the Footswitches. The active effects in each preset are indicated by
lighted LEDs in the Effect Matrix. The RP350 comes with 70 User presets (U1-U70) 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 RP350.

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
RP350.
3. Connect the other end of the PS0913B power supply to an AC outlet. Turn the RP350’s Mas-
ter 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 RP350’s Master Level knob to achieve the desired volume.

Section Two - Editing Functions
Editing/Creating Presets
The RP350 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 31) based on different musical styles. The Effects Library knob will then let you select
from a palette of effects chains (see page 31), 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.

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.
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 RP350 will revert to the stored values for
the preset.

12
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 U1-U70). 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.

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.

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 Three - Models and Parameters
About the Models
The RP350 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 RP350 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 RP350 can be programmed to suit your personal taste
and application. Understanding how these components alter the sound, and how each parame-
ter alters the effect, will help you achieve the sound you are looking for. The following overview
of the RP350’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:
(gives a single coil pickup the warm tone of a humbucker), and  (gives a
humbucker the unique sound of a single coil). Press this knob to turn Pickup modeling on
and off.
USB/RP Mix (When connected to a computer via USB) - Knob 2 adjusts the output
mix between the RP350 and playback from the computer. Ranges from  - 
- .
USB Level (When connected to computer via USB) - Knob 3 adjusts the RP350’s
recording level sent to the computer. Ranges from  to 
Preset Level - Knob 6 adjusts the preset’s level. Ranges from to .
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:  (DigiTech®Full
Range Wah sweeps the entire spectrum of audible frequencies),  (Cry Wah is a
traditional sounding Wah), and (based on a Vox®Clyde McCoyTM Wah). Press this
knob to turn Wah models on and off.
Wah Minimum - Knob 2 adjusts the Wah Pedal Minimum. Ranges from (toe up) to
 (toe down).
Wah Maximum - Knob 3 adjusts the Wah Pedal Maximum. Ranges from (toe up) to
 (toe down).
Wah Level - Knob 6 adjusts the Wah Level. Ranges from 0dB to +12dB.

14
Compressor
A Compressor is used to increase sustain, tighten up guitars, and prevent the signal from clip-
ping the input of other effects. It sets a maximum boundary for the strength of a signal.
Comp Model - Knob 1 selects one of two Compressor models:  (DigiTech®
Compressor),  (Based on a Boss®CS-2 Compressor/Sustainer), or 
(Based on an MXR®Dynacomp). Press this knob to turn the selected Compressor model
on and off.
