Cool little fuzz. The girth knob when turned up makes it more gated/spitty. So this pedal doesn't really have any sort of eq control and is a fairly barebones fuzz. Maybe it's a good fuzz to mod and add a muffin crumb tone control or something?

I was able to fit it into a 1590b instead of the 125b. I love that it has an easy test point for biasing. I screwed myself over on the led placement. I should have just did it inline with the top row pots/template. I just used the 125b template but held it over the pedal accordingly when I used my center punch.

Thanks for the report. This one is on my agenda

Trying it out with some mp38a's ;D
Hfe ~45-55 for the first transistor, ~75-85 for the second seems to be working best for me.
Not nearly as controllable. Kind of have to max the gain. I'm using the 5v pin as vcc and the bias knob is fairly useful to help balance with the girth but it seems to have a best spot anyway.
Still haven't tried a muffin crumb tone control+recovery stage, not sure if I have the parts around but will probably check tomorrow.

Edit: My highest hfe ones are only like 80 so using both of these cuz it needed more gain, and r3 100k instead of 120 now.
