I opened my trogotronic pedal and realized that its so bulky only to fit the big board which is practically unused. Its a radioshack large pcb and has lots of room. The only thing I dislike about this pedal is there's no master volume.

Anyone have a circuit I could add that'd work as a volume control?

Never heard of Trogotronic until just now. Interesting.

If you want to add a volume control, all you need is a 100K pot. Attach the circuit board's output wire to lug 3 of the pot, connect lug 2 of the pot to the bypass footswitch (where the board output wire used to be), and connect lug 1 to ground. Done.

If you post some gut shots, I can give you more specific help.

Okay, I think I can manage to do this. The wires are color coordinated but the stomp switch is something I've never seen. It has six lugs instead of nine.

Ill post guts perhaps anyway. Circuit is pretty minimal for what the thing does.

Right, that's what I was thinking. I knew they existed, but I haven't seen one that looked like a 3pdt before. Then again, I never searched.

thankyou for this. I was wondering but I didn't want to start a thread, I'm already a post whore. whats the difference in doing it this way or just a 2 wire pot inline with the output? I have seen it done both ways and I'm not really sure whats good or bad. some pedals even choke the power supply for master volume. I'm a noob but I want to learn.

If it's inline, that's series resistance rather than a voltage divider (3 wires). I suppose it would somewhat change the frequency response vs a voltage divider tied to ground, but also you might not have enough total resistance to completely quiet the output. But I think going with 1M would probably make it work on anything. 100K might not be enough for something like a SHO.
