A phase pedal is just a phase pedal, right? Not to the guitar fanatics of the rock 'n' roll underground of Salt Lake City. DigiTech decided to create Hyper Phase, which offers seven different phase shift types to choose from. By simply rotating the Type knob, you can select from 4-stage, 8-stage, and 12- stage phase shifting, Rise/Fall, Trigger up, Trigger down, and Step phase shift effects. This menu will not only deliver the Classic Phase sound, but will also give you Vibro and Falling Phase as well as a Steps sound. You have full control of the phaser by using the speed, depth, and regeneration knobs and can run the pedal in mono or stereo.
