Use the DigiTech RP255 pedal to get virtually any sound you want, just like the pros. With the RP series of guitar multi-effects units, Digitech have created a rich palette of quality sounds, coupled with genuinely useful creative tools such as the 20 second looper and drum machine. The DigiTech RP255 guitar multi-effects pedal packs 94 great amps, cabinets, and effects into its compact metal chassis, while letting you record directly or run through your live rig. One of the reasons that the new Digitech multi-effects units sound so good is that they are armed with the new AudioDNA2 chip. There are many patches, and you can get lots of different sounds out of this pedal.
According to several user reviews of Digitech RP255 guitar multi-fx, some users have praised it for the Good selection of effects; Responsive; many patches; very reliable. But some users also have complained for the Difficult To Use; Hard to navigate; Foot switches close.

To restoring the factory settings of Digitech RP255 multi effects, first power on while simultaneously holding the Store button and release the button when the display appears “FACRST”. Press and hold the Store button again for 3 seconds until “RSTORD” appears in the display and release it.
After restoring the factory settings is complete, the Expression Pedal calibration procedure now commences.
Expression Pedal Calibration:
To calibrate the Digitech RP255’s Expression Pedal, first press and hold the Up/Down Footswitches until “PDLCAL” appears in the display. When “TOE DN” appears in the display, rock the Expression Pedal forward (toe down) and press either Footswitch. And when “TOE UP” appears in the display, rock the Expression Pedal back (toe up) and press either Footswitch.
The Display now prompts you to calibrate the V-Switch sensitivity (VSwxxx), 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 (wahOFF). If the V-Switch is too sensitive, press the right Up Footswitch to raise the threshold (range is 0-200). Keep testing the V-Switch sensitivity and adjust the threshold until it only engages when you want it to. When the V-Switch sensitivity is set to your satisfaction, press both Up/Down Footswitches simultaneously to exit.
Warning! This procedure will erase all custom User presets, and recalibrates the Expression Pedal. Be sure you want to erase the memory and return the RP255 to its factory default state before continuing with this procedure. Hopefully the article of “Hard Reset Digitech RP255 to Restore Factory Settings” was useful.
