The RP55 from DigiTech is an amplifier modeling/multi-effects processor designed for the electric guitar. Inside the floor pedal is an AudioDNA DSP processor, providing 11 amplifier models and a host of other effects, 20 in total, 8 of which can be used at once, for creating your signature sound.

The user interface provides simple, straight forward editing functions. Plug your expression pedal in for control of whammy, wah or volume functions. The 30 pattern drum machine is a great tool for polishing up timing, using different patterns and tempos while the integrated chromatic tuner allows for quick tuning. Best of all, once you find the right sound combinations, it is easy to store them for later use with the 40 factory and 40 user presets.
