SUNN: Sunn Buzz SB-1G

The Sunn Buzz is an odd little fuzz from the mid-to-late sixties.   It's silicon and runs on a single AA battery (1.5v) with a topology vaguely similar to the Fuzztone.  The design was fairly questionable - the fuzz box had to be plugged into the amp input jack, which would have been fairly limiting.
