It's been a while... Hope all's well with everyone. I'm somewhere between "still building" and "retired", with no good idea of what "retired" might actually mean...
Thought I'd share an easy mod with you. I discovered it by putting the wrong size of capacitor in a build and ended up with something very different that I liked better than the correct circuit. Maybe some of y'all will enjoy it, too.
In the Foxx Tone Machine / Wolfshirt, there is a 1n capacitor between the base of Q1 and emitter of Q2 (C3 in the Wolfshirt schematic). Instead of 1n, make it 100n. The result doesn't really remind me of any other pedal circuit I can think of off the top of my head. Dark and nasty OD with an octave? I only tried it with single coils, not humbuckers yet. It might get pretty heavy with humbuckers. I have it on a switch to go between the original 1n or adding the 100n in parallel to it. Probably the easiest way to try it is to temporarily tack the 100n onto the back of the 1n to give you 101n. To really do it right, perhaps the tone control should be tweaked a bit, but it's OK enough as it is that I've lost a couple afternoons with nothing much to show for it other than a smile. "Beware of the dark side."
I'm gonna have to give that a try, once I find that Wolfshirt I populated a few years ago. I never boxed it because I have having too much fun with my vero Foxx Tone Machine. Well technically its in a box with a bunch of other unfinished & un-started boards.
Cool. I'll have to breadboard that one up. Not sure if I've got a Wolfshirt board or not.
