Heard on numerous classic recordings by players like Jimi Hendrix, David Gilmour and Robin Trower, the Uni-Vibe is essentially a four-stage phase shifter.
However, without going into a full-blown technical explanation, the components and circuit have certain quirks that distinguish it from a run-of-the-mill phase shifter.
For decades, the only viable choices for guitarists seeking authentic classic Uni-Vibe effects were to hunt for an original vintage unit or buy a boutique version, but both options were expensive. The new MXR M68 Uni-Vibe Chorus/Vibrato solves this dilemma once and for all by providing genuine Uni-Vibe effects with thick, rich swirling textures in a pedal that costs less than half of the price of most acclaimed boutique versions.
