This is a special 1969 Shin-ei Uni-Vibe with the gray cord, white Uni-Vibe name painted indicating it is the same type used by Jimi Hendrix at Woodstock and with Band of Gypsys and by Robin Trower for Bridge of Sighs. The later 70s era black cord ones with silver name stencil don't sound near as good or lush. It has a manual speed controller taking up less pedal board space and is in near museaum quality condition for an effect that is over 40 years old and still works as good as the day it was made. Nothing made today comes even close to the original circuit thought they all claim to as do their fans who've never owned a real one. This is a the real issue. Accept no imitations. Contact me if interested.
