The Bee Gee was release in 1975, or so I’ve read. It is a fairly original design, and you can see the origins of the Boss DS-1 in it, which was released in 1978. The Jet Phaser features the same circuit. It is really more of a distortion.
You may be confusing it with the Bee Baa, which is an earlier design, completely different, and a much gnarlier fuzz. I could see it sounding fuzzrite ish.
