Meet the Combatants

MXR M68 Uni-Vibe Chorus/Vibrato

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.

MXR M101 Phase 90

This device has found its way into many of Eddie Van Halen's recordings, adding a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. Not just for guitars; it works well with bass, keyboards and even vocals. Vary the speed from a subtle, long cycle to a fast, watery warble...and myriad vintage vibrations in between.

Voting Closed!

The MXR M101 Phase 90 (60.68 percent) destroyed the MXR M68 Uni-Vibe Chorus/Vibrato (39.32 percent) to advance to the next round! To see the current matchup and all the matchups that have taken place so far, head HERE. Thanks for voting!
