I bought this new at Mannys Music on 48th Street in Manhattan sometime between 1976 and 1978. I probably have the receipt somewhere. I used it twice. The second time was yesterday.  These early versions are like KLONs....Extremely rare with some kind of transistor that was used only in the 7115 to 7864 serial number range until the Russians bought them all up for Safety Systems installed in Chernobyl.  Probably.   Good for tone/Not so good for nuclear reactors.

Jimi Hendrix once stood in front of the exact same display case that this Flanger was in. If he sneezed into the display his DNA could be on the box!    I may have opened the box ten times since I have owned it.  To take it out and put it back inside.  Some of Jimis DNA may have escaped but I cannot be sure.  I like the Fulltone version of the Univibe better and thats what I use for any modulation kind of effect.  

This one goes to eleven,

Viintage Via Pizza box included.
