My father gave me this pedal which he had from his gigging days (early to mid-70s) and I haven't been able to find any information on it other than a closed auction and a few pictures here and there. It's in pretty good condition other than the missing dot, and it sounds great. Just wondering if anyone else has one or knows anything about it.
Here is the inside. I looked for a pot code so I could date it at least but couldn't find one.
