2

When you first apply power to the RP250, it powers up in Performance mode. Performance mode 

provides access to all of the presets within the RP250 via the Up and Down Footswitches.  

Knob 1 selects a tone from the Tone Library, Knob 2 selects an effect from the Effects Library, 

Knob 3 adjusts the Effects Level, and Knob 4 adjusts the Master Level (volume).

The RP250 presets can be bypassed via a true analog bypass circuit for a clean, unprocessed guitar 

signal.  To bypass the RP250, press both Footswitches simultaneously.  The Display reads Bypass 

indicating the preset is bypassed.  Press either Footswitch to exit Bypass and return the RP250 

to the last preset used. 

The Tuner in the RP250 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 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).  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 either 

Footswitch.
