Delivers chewy, Leslie-sounding goodness from a smaller footprint pedal. The Vibe switch selects either Chorus Mode - dry signal mixed with pitchshifted signal or Vibrato Mode - only pitch-shifted signal. Then use the level control to set the effect volume, the speed control to set the sweep rate and the depth control to set overall intensity. Heavy duty Phase 90 sized housing perfect for taking this lush, swirly pedal out on the road. True hardwire bypass. Powered by 9 volt battery or AC adaptor.
