The Digitech Whammy, with its high functionality as an effects unit, excels as a pitch shifter. I think it's in good condition. The Whammy knobs have been replaced with MXR-type knobs and rubber grips, allowing for foot control. Rare step sequencer included MIDI cable included Instruction manual included, center negative 9V The Whammy goes "peep peep" It's a random effect. A rare item.
