About the RP150
Performance Mode
When you first apply power to the RP150, it powers up in Performance mode. Performance mode
provides access to all of the presets within the RP150 via the Up and Down Footswitches.
Knob 1 selects a tone from the Tone Library, Knob 2 selects an effect combination from the Ef-
fects Library, Knob 3 adjusts the Effects Level, and Knob 4 adjusts the Master Level (volume).
Bypass Mode
The RP150 presets can be bypassed via a true analog bypass circuit for a clean, unprocessed guitar
signal. To bypass the RP150, press both Footswitches simultaneously. The Display reads
indicating the preset is bypassed. Press either Footswitch to exit Bypass and return the RP150
to the last preset used.
Tuner Mode
The Tuner in the RP150 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 indi-
cate 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. Exit tuner mode by
pressing either 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 and dropped tunings. Alternate tunings are
A=453Hz to A=427 Hz (displayed as to ). Dropped tunings are A=A flat (displayed as ),
A=G (displayed as ), and A=G flat (displayed as ). The display window will briefly flash the cur-
rently selected tuning preference.
Exit Tuner mode by pressing both Footswitches simultaneously.
