The Uni-Vibe® Chorus/Vibrato is one of the most iconic effects in music history. Since the late 60s, groundbreaking guitar players have used it to expand the tonal and textural palette of the electric guitar. The MXR team has just remastered the classic effect for modern players. The MXR Chorus/Vibrato delivers the same chewy, Leslie-sounding goodness with a smaller footprint. With its simple three-knob interface, you can dial up the iconic effect to your taste in short order. First, use the VIBE switch to select either Chorus Mode dry signal mixed with pitch-shifted 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. The MXR Uni-Vibe Chorus/Vibrato comes in a Phase 90-sized housing a fraction of the size and weight of the original Uni-Vibe pedal and features true bypass switching. Perfect for taking this lush, swirly pedal out on the road.
