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
3
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.

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.

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.

Section Two - Editing Functions
Editing/Creating Presets
The RP70 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 buttons. The Tone
Library button gives you access to a variety of pre-programmed amp/distortion tones (see page
37) based on different musical styles. The Effects Library button then lets you select from a pal-
ette of effects chains (see page 38), from simple delays to full multi-effect signals with modulation,
delay and reverb. Use the Effects Level Button 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 select individual Effects, and the Value
Up/Down buttons to adjust their settings.
To edit and create a custom preset:
Use the Footswitches to select the preset you wish to edit. If you are trying to find some-
thing different from the existing presets, begin by using the Tone Library, Effects Library,
Effects Level and Value Up/Down buttons to get close to a sound you want.
Once you have a sound close to what you are after, begin editing the Effects by pressing the
Edit Up/Down buttons and selecting the Effect you want to adjust.
To turn an Effect on, select it with the Edit Up/Down buttons. Each Effect has multiple set-
tings to select from. Use the Value Up/Down buttons to change the values for the selected
Effect To turn an Effect off, press and hold the Value Down button until appears in the
Display. (For EQs, , , and  are the settings with no boost or cut.)
1.
2.
3.
18
Anytime a stored value within a preset is changed, you need to store the changes (with the Store
button), or the changes will be lost. Changing presets, or turning the power off before storing any
changes erases any edits made and the RP70 will revert to the stored values for the preset.
Storing/Copying a Preset
Once the preset has been modified to your liking, you may store your settings to any of the
50 User preset locations (presets 1-50). The following steps outline the procedure for storing
changes to a preset or copying a preset to a different location:
Press the Store button once and the current Preset location will flash in the Display. This
is asking you to select a new User Preset location where your new sound will reside.
If desired, select a new User Preset location using the Footswitches.
Press the Store button again to save the changes.
The procedure for copying one Preset to another Preset location is the same. Simply use the
Footswitches to select the Preset that you want to copy, then follow the steps listed above.

Section Three - Models and Effects
About the Models
The RP70 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 RP70 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 RP70 has multiple settings to select from. Use the Value
Up/Down buttons to change the values for the selected Effect. The following overview of the
RP70’s Effects outlines the settings each Effect contains.
Pickup/Wah
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. Wah is an ef-
fect controlled by an optional Expression Pedal making the guitar sound as if it’s saying “Wah.” See
page 32 for information on how to link the Wah effect to an Expression Pedal.
The Pickup/Wah settings are:

EQ
The RP70’s EQ helps further shape your tone with Bass, Midrange, and Treble controls. The EQ
settings are:
 Bass tone control. - cut bass frequencies by –12dB, –9dB, –6dB, and –3dB
respectively.  has no boost or cut. - boost bass frequencies by 3dB, 6dB, 9dB,
and 12dB respectively.
 Midrange tone control. - cut midrange frequencies by –12dB, –9dB, –6dB, and

respectively.  has no boost or cut. - boost treble frequencies by 3dB, 6dB,
9dB, and 12dB respectively.
Noise Gate
The Noise Gate effect includes two models: a Silencer gate and an Auto Swell gate.
A silencer gate is designed to eliminate noise while you are not playing. The Silencer gate’s nine
settings () determine the threshold, which determines how loud a signal must be before it
can be heard. The higher the setting, the louder a signal must be in order to be heard.
The Auto Swell provides an automatic volume swell effect. The auto swell’s nine settings ()
determine the attack time (how quickly the swell grows from the note you play). The higher the
setting, the faster the swell grows.
The noise gate settings are:

 Silencer gate.  is the lowest threshold,  is the highest threshold.

 Auto Swell gate.  is the fastest attack time,  is the slowest attack time.
Chorus/FX
The Chorus/FX model actually contains twelve different modulation and pitch effects (described
on the following pages). Each effect includes nine settings which include a variety of configurations
that generally range from more subtle (lower settings) to more extreme (higher settings). The
Chorus/FX settings are:

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 RP70 Chorus effect
includes a model based on the classic Boss® CE-2 Chorus and the DigiTech’s Dual Chorus. Chorus
settings are:
 Boss CE-2 Chorus.
 Dual Chorus.
27
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. Settings are .
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. Settings are .
Tremolo
A Tremolo effect modulates the volume of the signal at an even rate. Settings are .
Panner
A Panner modulates the sound from left to right at an even rate. Settings are .
Vibrato
A Vibrato effect modulates the pitch of the incoming signal at an even rate. Settings are .
Rotary Speaker
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
28
going away from the listener. Settings are .
YaYaTM
AutoYa combines the characteristics of a Wah and a Flanger, creating an almost human vowel char-
acteristic as if the guitar were saying “Yah.” Control the effect with an optional Expression Pedal.
Settings are .
AutoYa™
Similar to the YaYa effect described above, AutoYa™ automatically provides this animation to the
sound at an even rate. Settings are .
Step Filter
The Step Filter is like an automatic “random wah” with a square waveform. Settings are .
Envelope Filter
The Envelope Filter is a dynamic Wah effect that alters your sound based upon how hard you play.
Settings are .
Detune
A Detuner makes a copy of your incoming signal, takes the copied signal slightly out of tune from
the original, then mixes the two signals together. The result is a doubling type of effect as if two
guitars were playing the same part together. Settings are .
Pitch Shift
A Pitch Shifter copies the incoming signal, then shifts the pitch of the copy to a different note. The
shifted note is then mixed back with the original signal, sounding as if two guitars were playing dif-
29
ferent notes. Settings are .
DigiTech® Whammy™
The DigiTech® WhammyTM is an effect that uses an optional Expression Pedal to bend the pitch
of the incoming signal, or add a bendable harmony with the original signal. As the Pedal is moved,
the note bends either up or down. When DigiTech Whammy is selected, it is automatically placed
before the Amp modeling as shown in the block diagram on page 20. Settings are .
Delay
Delay is an effect that will record a portion of the incoming signal, and then play it back a short
time later. The recording can repeat just once or several times.
The RP70 offers four different delay models (Analog Delay, Digital Delay, Pong Delay, and Tape
Delay), each with 5 seconds of delay time available. There are two different parameters used to
program the delay: Delay Variation and Delay Time. The first parameter of the delay effect is Delay
Model type and Variation, which varies the amount of feedback (number of repeats) and level. The
second delay parameter is Delay Time. This is indicated by a value 1-99 (10ms-990ms), 1.0 - 5.0 (1
- 5 seconds respectively in 100ms increments) in the Preset Number display when the Delay LED
is lit. Delay settings are listed on the following page.

Section Four - Other Functions
Optional Expression Pedal
The rear panel of the RP70 includes an input for an Expression Pedal. Any passive volume pedal
can be used as an Expression Pedal with the RP70. Connect the output of a passive volume pedal
to the Control In jack on the RP70. The Expression Pedal can be assigned in each preset to
control the Volume, Wah, DigiTech® WhammyTM, YaYaTM, or one of several other parameters in real
time with your foot. When a parameter has been assigned to the Expression Pedal, a program-
mable minimum and maximum value can also be assigned. The procedure for assigning a parameter
to the Expression Pedal is as follows:
Press either Edit Up button until the Expression LED lights up. An effect LED will also light
indicating which effect the Expression Pedal is currently assigned to.
Press either Value Up/Down button until your desired effect’s LED is lit in the matrix. The
Expression LED will stay lit during your selection and the Display will show a two-digit char-
acter value to describe the effect parameter that the Expression Pedal is assigned to.
Once you have assigned a parameter, you can set the control range of that parameter. Press
the Edit Up button again. The number value shown is the minimum parameter value – this is
the value that will be reached when the Expression Pedal is rocked back (toe up).
Press the Edit Up button again. The number value shown is the maximum parameter value
– this is the value that will be reached when the Expression Pedal is rocked forward (toe
down).
Use the Store procedure (see page 18) to save your changes to the preset.

data will be lost forever! Be sure you want to erase the memory and return the RP70
to its factory default state 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 RP70.
2. When the display prompts you with , release the Store button.
3. Press and hold the Store button for 3 seconds until  appears in the display and release. The
Factory Reset procedure takes approximately 10 seconds.
