DigiTech RP90 Guitar Multi-Effects Pedal

At the heart of the new RP90 is DigiTech's AudioDNA2 DSP engine, offering four times the power as the previous AudioDNA processor.

AudioDNA2 is a proprietary audio ASIC used to provide maximum accuracy in the tone and dynamic response of these new RP Series processors.

The RP90 adds an expression pedal for control of effects parameters.
