In actual fact, the Uni-Vibe really doesn't sound all that much like a Leslie. But thanks to artists such as Robin Trower and Jimi Hendrix, the Uni-Vibe is firmly entrenched in rock 'n roll history as a superb effect in its own right. While no longer made by Univox, you can still obtain this incredible sound from effects made by other manufacturers.
The Uni-Vibe is an under-used item in the guitar player's arsenal. It'll make your rhythm chops come alive and add an extra dimension to your solos. It'll also spice up your recordings!
A selected Uni-Vibe discography:
Jimi Hendrix: Machine Gun
Jimi Hendrix: The Star Spangled Banner (opening)
Robin Trower: Bridge of Sighs
Robin Trower: Day of the Eagle
Robin Trower: Too Rolling Stoned (slow, phasey end solo)
Grand Funk: Locomotion (guitar solo)
Tips for Uni-Vibe users
Tip 1: Since the effect relies on opto-electronics, use an AC adapter whenever possible. The light source that is the heart of the Uni-Vibe sound will wear down batteries fairly quickly.
Tip 2: Open (i.e., first position) chords sound particularly nice on the slow setting.
Tip 3: The modern versions of the Uni-Vibe are often offered with a stereo option. This allows you to run the signal to separate amplifiers, one placed at each end of the stage, for a truly s-p-a-c-i-o-u-s sound.
Tip 4: This is an effect that can actually become part of your everyday sound. Remember Robin Trower's Bridge of Sighs and In City Dreams albums? The Uni-Vibe was prominently featured on virtually every song. Did you get tired of the effect? No, you actually came to expect it.
Tip 5: The Uni-Vibe, like other modulation effects, often sounds best when used at the end of your signal chain. Use it after compression, fuzz, overdrive, etc.
