Introduction

The Presets

Presets are named and numbered locations of programmed sounds which reside in the RPx400. Presets are
recalled with the footswitches. The active effects in each preset are indicated by the lighted LEDs in the
Effect Matrix. The RPx400 comes with 40 User Presets (Presets U1-U40), 40 Factory Artist Presets (Presets
A1-A40), and 40 DigiTech factory presets (F1-F40). The User Presets are locations where you can store your
edits. You may not store changes to the Artist/Factory Presets. From the factory, the 40 User Presets are
exact duplicates of the 40 Factory Artist Presets.

Performance

When you first apply power to the RPx400, it powers up in Performance mode. Performance mode provides
access to all of the presets within the RPx400 via the Up and Down Footswitches. The Number 1 Knob
(left) adjusts the Gain for the selected Amp Type, the Number 2 Knob (second from the left) adjusts the
amount of Bass enhancement, the Number 3 Knob (middle) adjusts the amount of Mid-range enhancement,
the Number 4 Knob (second from the right) adjusts the amount of Treble (high frequency) enhancement, and
the Number 5 Knob (right) adjusts the Master Level (volume).

Bypass

The RPx400 Presets can be bypassed for a clean, unprocessed guitar tone. To bypass the RPx400, press both
the Up and Down Footswitches simultaneously. The display read Bypass indicating the preset is bypassed.
Pressing any of the 3 Footswitches exits Bypass and returns the RPx400 to the previously selected preset.

ing the Up and Down Footswitches simultaneously. The display briefly shows tuner 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).

A=440). Rotate the Number 1 Knob to select alternate dropped tunings. Alternate tunings are A = Ab , A =

The output is muted in Tuner mode. The Expression Pedal returns sound to the output allowing signal to be
heard while tuning. Exit tuner mode by pressing any of the 3 Footswitches.
