RP355 FAQs

The Expression pedal does not function.
Perform the 'Expression Pedal Calibration' procedure located in the RP owner's manual.
How do I switch between Stomp Box and Preset mode?
To switch between Stompbox and Preset modes, quickly press and release the Up Footswitch and Amp A/B Footswitch simultaneously. The RP355 will briefly display 'Stomp' for Stomp Box Mode or 'PRESTS' for preset mode.
The Unit turns on but I do not get any sound out.

Verify the correct power supply is being used to power the unit.
