One of the Most Recognizable Guitar Effects Ever Returns

Add the unmistakable sound of the classic Uni-Vibe effect to your pedalboard with the MXR Uni-Vibe Chorus/Vibrato pedal. It's one of the most recognizable electric guitar effects ever, with a warm, undulating tone that's incredibly addictive to play through. And because you're unlikely to find an original Uni-Vibe in working condition for a reasonable price at Sweetwater or anywhere else, MXR has remastered this iconic effect to bring it to a whole new generation of sonically-adventurous guitarists. Plug the MXR Uni-Vibe Chorus/Vibrato into a tube amp set to its breakup point, and you've got tone that'll make anyone take notice.

MXR Uni-Vibe Chorus/Vibrato Pedal at a Glance:
  • Take your chorus effect from subtle to extreme
  • Much more pedalboard-friendly than the original
  • Maintain your tone with true bypass switching
Take your chorus effect from subtle to extreme

You can coax all manner or rich chorus effects from the MXR Uni-Vibe's chorus mode, from subtle shimmers to slow sweeps. This mode blends your dry guitar signal in with the chorus effect. For the classic extreme Uni-Vibe effect, hit the Vibe button to take your dry signal out of the effect. Using the rate and depth knobs, you'll be able to dial in everything from unsettling vibrato to a mind-bending, throbbing effect.

Much more pedalboard-friendly than the original

It's a good thing that MXR didn't emulate the original construction of the Uni-Vibe, because that would make the MXR Uni-Vibe Chorus/Vibrato much less compact. This reissue is pedalboard friendly, with a simple three-knob interface that makes it easy to dial in great tone quickly.

Maintain your tone with true bypass switching

Tonal purists will appreciate the Uni-Vibe Chorus/Vibrato's true bypass switching. When the effect is bypassed, your guitar signal bypasses the pedal's internal circuitry so that your tone remains truly unaffected.

MXR Uni-Vibe Chorus/Vibrato Pedal Features:
  • Reissue of the classic Uni-Vibe electric guitar effect made popular in the '60s-'70s
  • Wide range of effects between the chorus mode (dry signal and pitch-shifted signal) and vibe mode (pitch-shifted signal only)
  • Easy to add to your pedalboard thanks to the compact design
  • Your tone won't be affected while the pedal is off thanks to true bypass switching
  • Easy to dial in with the simple three-knob interface
The Uni-Vibe is back in the MXR M68 Uni-Vibe Chorus/Vibrato pedal!

Oh HELL yeah

You heard it, Trower and Hendrix, it's true, hit a note or chord and just stare at your guitar, yes that's you playing not Robin or Hendrix but if you close your eyes and just listen to those notes ring out, especially with, your there.

Hendrix/Trower Psychedelia to the Max!

Love this pedal. Ordered from Sweetwater (of course). This thing brings back sooooo many memories. If you own Bridge of Sighs, the epic desert island disc from Robin Trower, you know what this pedal sounds like. It also conjures up some other great sounds used by the masters Hendrix, Page, Lifeson, and others from the heavy psychedelic era. Wonder what Jimi was using when he ripped the "Star Spangled Banner?" Plug into this bad boy and voila... you got it pegged. If you're looking to add that sumthin sumthin that your flanger or phase 90 just doesn't do for you... this is your solution. Watery, trippy, stoner rock jam machine!

My review, as requested

Absolutely great, either with Strat single coils, or a pair of humbuckers. The neck position will put you in ethereal space out near Jupiter. I've been after this sound in my head for decades.

Awesome Uni-Vibe!!

I've been waiting for Dunlop/MXR to reissue the Uni-Vibe since it was discontinued a few years back. I was excited to see it while looking at new gear online from the NAMM 2014 show. I pre-ordered it from Sweetwater as soon as it was made available. Just received it a few days ago and I gotta say it is a great pedal. Sounds very close to the older Dunlop Uni-Vibe, only in a Phase 90 sized stompbox. It absolutely nails the Hendrix, Gilmour, Trower tones. Has a lot of depth/throb. I've tried a few cheaper Uni-Vibe style pedals such as the Danelectro Cool Cat Vibe and the Moen Shaky Jimi. This one blows them away. Although this reissue uses FET technology rather than a photo lamp, it doesn't sound like a glorified phaser. It actually sounds like a vintage Uni-Vibe. Very well done MXR.

I own an original Uni-vox Univibe from the 70's. This little box sounds fine to me. It fits on a board in a much smaller space. Many have tried to get THAT SOUND before. The original has a footpedal for speed. This does not. This may be considered to be a 1.5 trick pony. But it sounds good to me!
Music background: I have been playing since 1963.

Sweetwater Advice

MXR M68 Uni-Vibe

If your tastes lead you to the more psychoactive realms of the chorus effect, the MXR is capable of some very twisted and unorthodox tones....
