The digital section has: pitch shift, whammy, a Harmonizer (original not/ selected interval note), dual detune, mono detune, smooth whammy, smooth pitch, sampler and arpeggiator. Also has various mixers, great modulation effects: Chorus, Phasers, Flangers, Tremolos and auto panners too. The Wah Wah is okay, but you really need to spend time to nail the sweep of the tones you want. I've tried Korg, Boss, newDigiTechs, other units out there and this unit doesn't have all the conveniences (bells and whistles) of todays unit's, but sound wise, the RP12 is still the best.
