Yeah, I emailed Mike but he was only concerned if it dropped volume. He also suggested upping the voltage from 9 to as high as 18. I did this and the pedal sounds better but I still have a boost in volume. And it's not a slight increase it is as much as my Timmy at unity gain and the gain set at noon.
Sorry, volume at unity gain.Either I'm missing something, or you meant something different than what you wrote. If the Timmy is at unity gain it is neither boosting or cutting the signal.
Just what I was about to write, Phillipe. Any true bypass pedal can be easily modded for this. Take the pcb output wire and disconnect it where it hits the stomp switch. Connect it to lug 3 of a 100k trim pot. Lug 2 goes to the stomp now and lug 1 to ground. Boom. Instant volume control.
Non TB pedals are trickier, as the bypass and effect signal can be altered at once. Not good.
Sorry, volume at unity gain.
If it's doable then you can drill a hole in the side ala the earlier Skreddy pedals or just solder it direct to the stomp or on a little daughter board. Then it would be a set and forget inside the pedal with no external drill hole.. Though I'm not sure the mxr is truebypass from memory. Then you need to convert it to tb and do the mod.
