About the RP70
Performance Mode
When you first apply power to the RP70, it powers up in Performance mode. Performance mode
provides access to all of the presets within the RP70 via the Up and Down Footswitches. The
Edit Up/Down buttons cycle through the effects in the matrix.
Edit Mode
When you select an Effect with the Edit Up/Down buttons, you can adjust the Effect with the
Value Up/Down buttons. (For descriptions of the Effects and their parameters, see page 20.)
When you make changes to a preset’s Effects, you must store the changes or they will be lost
when you select a different preset or disconnect power to the RP70. See page 18 for a description
of the Store procedure.
Bypass Mode
The RP70 presets can be bypassed for a clean, unprocessed guitar signal. To bypass the RP70, press
and release both Footswitches simultaneously. The Display reads  indicating the preset is
bypassed. In Bypass mode, all buttons are disabled. Press either Footswitch to exit Bypass mode
and return the RP70 to the last preset used.
Tuner Mode
The Tuner in the RP70 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 
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 left 6 red LEDs indicate the note is flat and should be
tuned up. The right 6 red LEDs indicate the note is sharp and should be tuned down. The center
LED indicates the note is in tune. The output is muted in Tuner mode; rock the Expression Pedal
to regain volume.

In Tuner mode, you can change your tuning reference with the Vallue Up/Down buttons. The
default factory setting is A=440 Hz (displayed as ). Other tuning references are A=A flat (dis-
played as ),A=G (displayed as ), and A=G flat (displayed as ). The display window will briefly
flash the currently selected tuning preference.
Exit Tuner mode by pressing either Footswitch.

Tone Library Button
You can press this button at any time (except in Bypass or Tuner mode) to access the Tone Library,
and then use the Value Up/Down buttons to select from a variety of genre-based amp tone
defaults ranging from Blues to Metal to Country. Behind the scenes, the Compressor, Distortion,
Pickup/Wah effects, Amp/Cabinet model, and EQ are configured to create a specified tone. You
can further refine the sound by editing the preset (see Editing/Creating Presets on page 17). Chang-
ing 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 Button
You can press this button at any time (except in Bypass or Tuner mode) to access the Effects Li-
brary and then use the Value Up/Down buttons to select from 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 17). Changing between different Effects Li-
brary 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 Button
You can press this button at any time (except in Bypass or Tuner mode) to access the Effects Level.
This button 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 increasing this button’s value increases the level
of these effects and decreasing its value decreases the level of these effects.
Master Level Button
Press this button and use the Value Up/Down buttons to set the overall output level of the RP70.

To learn about storing changes to presets, see page 18.
Presets
Presets are numbered locations of programmed sounds which reside in the RP70. Presets are re-
called with the Footswitches. The active effects in each preset are indicated by lighted LEDs in the
Effect Matrix. The RP70 comes with 50 User presets (1-50) and 50 Factory presets (51-00). 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 50 User presets are exact duplicates of
the 50 Factory presets. This allows you to create your own presets without losing the sounds that
came with the RP70.

These two Footswitches select presets, access the Tuner, or bypass the RP70. The
Footswitch on the right will select the next preset up, and the Footswitch on the left will
select the next preset down. Pressing both Footswitches together will bypass the currently
selected preset. Pressing and holding both Footswitches for 2 seconds will access the Tuner.
Press either Footswitch to exit Bypass or Tuner mode.
Tone Library, Effects Library, Effects Level, and Master Level Buttons
At the heart of creating presets in the RP70 are the Tone Library, Effects Library, and Effects
Level buttons. By pressing one of these buttons and using the Value Up/Down buttons,
you can select from 20 amp/distortion tones, 20 effects chains, or the overall post amp/dis-
tortion effects level respectively. The Master Level button accesses the master output vol-
ume parameter for the RP70. Each button is described in detail below.
Tone Library Button
The Tone Library button accesses a library of preset amp tones. Press this button
and then use the Value Up/Down buttons to select from a variety of genre-based
amp tones ranging from Blues to Metal to Country (see page 37 for a list of available
tones). Behind the scenes, the Pickup/Wah, Compressor, Amp/Distortion, and EQ are
configured to create a specified tone. You can further refine the sound by editing the
preset (see Editing/Creating Presets on page 17). Changing between different Tone Library
selections does not change the Chorus/FX, Delay, or Reverb settings, allowing you to
experiment with different amp styles quickly in the context of the current effect chain.
The Display will read  (for “custom”) when any of the associated effects have been
changed from a default library setting.

button and use the Value Up/Down buttons to select 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 17). Changing be-
tween different Effects Library selections does not change the Pickup/Wah, Compressor,
Amp/Distortion and EQ settings, allowing you to experiment with different effect chains
quickly in the context of the current amp tone. The Display will read  (for “custom”)
when any of the associated effects have been changed from a default library setting.
Effects Level Button
The Effects Level button lets you adjust the levels of post-amp model effects (Cho-
rus/FX, Delay, and Reverb). Press this button and use the Value Up/Down buttons to
change the relative level of the post-amp effects (Chorus/FX, Delay, and Reverb).Think
of it as an effects mix control where increasing this setting increases the level of these
effects, while decreasing this setting decreases the level of these effects.
Master Level Button
The Master Level button lets you adjust the output level of the RP70. Press this button
and use the Value Up/Down buttons to change the output level of the RP70.
Edit Up/Down
The Edit Up/Down buttons select which effect is to be edited. As each effect is selected,
the Display shows the effect setting. A decimal in the bottom right corner of the Display
turns on when a preset has been modified. The Edit Up/Down buttons are also used to
change the RP70 Drum Machine parameters (Note that Drum Machine settings are global
for all presets and are not saved with the preset).

Value Up/Down
The Value Up/Down buttons are used for editing effects, navigating Tone/Effects Libraries,
adjusting Effects and Master Levels, and adjusting Drum Machine settings.
Display
The Display provides information for different functions depending on the mode that has
been selected. In Performance mode, the Display shows the currently selected preset num-
ber. In Edit mode, the Display shows the value of the effect being adjusted. A decimal in
the bottom right corner of the Display turns on when a preset has been modified. In Tuner
mode, the Display shows the note being played.
