I've used Pedalgrinder slightly modified schematic on page 3.
Some suggested high gain, some low gain transistors.
Should test them both.

I built the 3080 version. It works and gets very distorted with the sustain all the way up. It's not a bad thing as it sounds like a great overdrive. I had one of the vintage units and seem to remember it sounding similar, but maybe not quite as much distortion.
ReplyDeleteThe original is distorted as hell. I had two, one powered by TWO 9v batteries. "Distortion less sustain" it said. Yeah, right..

ReplyDeleteI built the LM13700 version and it works, but I think tone 1,3 and sustain wires are the wrong way around (wrong on FSB schematic too).
ReplyDeleteI've built it for someone who used to own it back in the day so I'll report back when they've used it and can confirm.
