Expression Update
The RP500’s Expression pedal has the option to update its position each time a preset change
is made. The default behavior for the Expression pedal is to only update its position on a preset
change when the Volume Pre or Volume Post parameter is linked within a preset. This lets the
Expression pedal behave like a real volume pedal between preset changes. When Expression Up-
date is enabled (ON), the Expression pedal will update its position regardless of the parameter
linked, giving it more of an “analog” feel like a real expression pedal would behave.
To enable the Expression Update function, follow these steps:
1. Press the Edit button until the Expression row has been selected (indicated by the LED light-
ing on the Expression row).
2. Rotate Knob 1 to select EXPUPDAT. The default setting is for Expression Update is OF.
3. Press Knob 1 to enable or disable Expression Update.
Expression Update is a global function that affects the behavior for all presets. You do not need
to save this change to each preset.
Factory Reset
This function resets the RP500 to its original factory settings. This procedure erases all custom
User presets, and recalibrates the Expression Pedal.
ATTENTION: Performing this function will erase all user-programmed data. All
such data will be lost forever! Be sure you want to erase the memory and start
fresh 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 RP500.
2. When the display prompts you with FACt RST, release the Store button, which is now
flashing.
3. Press and hold the flashing Store button for 3 seconds until ReSTOReD appears in the
display and release. The Restore procedure takes several seconds to complete; during the
procedure, the display will count up. After the Restore procedure is complete, the Expression
Pedal calibration procedure will begin.
Expression Pedal Calibration
The Expression Pedal on the RP500 needs to be recalibrated for use after a factory reset has
been performed. This calibration procedure is automatically entered after a factory reset proce-
dure. (You can also initiate the calibration procedure by pressing and holding the BYPASS foot-
switch for approximately 5 seconds.) In the event the Pedal’s calibration fails, or if the Pedal does
not function properly, it can be re-calibrated using the Pedal Calibration procedure. This will not
erase the User presets. The procedure for Calibrating the Expression Pedal is as follows:
1. Press and hold the Bypass Footswitch until PEDALCAL appears in the display (BYPASS,
TUNER, and EXIT will be displayed before PEDALCAL is accessed, after about 5 seconds.)
2. When the Display prompts you with TOE DowN, rock the Expression Pedal forward (toe
down) and press Footswitch 5 (Reverb).
3. When the Display prompts you with TOE UP, rock the Expression Pedal back (toe up) and
press Footswitch 5 (Reverb).
4. The Display now prompts you to calibrate the V-Switch sensitivity (VSWitchxxx), where
XXX is the current V-Switch threshold. Rock the Expression Pedal forward and press firmly
on the toe once to turn the V-Switch on (WAH ON), and again to turn the V-Switch off (WAH
OFF).
5. If the V-Switch is too sensitive, press the Up Footswitch to raise the threshold (range is
0-199). The Down Footswitch decreases sensitivity. Keep testing the V-Switch sensitivity and
adjust the threshold until it only engages when you want it to (too sensitive a setting will lead
to the V-Switch falsely triggering on or off when using the Expression Pedal).
6. When the V-Switch sensitivity is set to your satisfaction, press Footswitch 5 (Reverb) to
exit.
Note: If the Display shows ERROR, an error has occurred and steps 2 through 5
should be repeated.
