These videos and audio files are bonus content related to the November 2014 issue of Guitar World. For the full range of interviews, features, tabs and more, pick up the new issue on newsstands now or at the Guitar World Online Store.

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.
