Univox
Uni-Vibe
Debut: 1969
Another stompbox made famous by Hendrix is the Uni-Vibe—an early rotary-speaker simulator that used a pulsating light source and four photo resistors to modulate its four-stage phase-shifting circuit. It’s primitive technology, but what would Band of Gypsys be without the Uni-Vibe’s thick, smoky swirl? Or, for that matter, Robin Trower?
