This pedal was reversed by myself, with the help of an interested party that had access to pictures of an original. He wishes to remain anonymous, and by consequence I have decided to only include the schematic I threw together in DIYLC, and title the thread with a modified version of the original pedal's name.
The board was gooped, and in the pictures I was given, the degooping process had destroyed the writing on two capacitors, so their values are not confirmed. The tone cap's likely value is listed with an asterisk. Some writing was left on the cap, and it appears to indicate .01. It's a subtractive control, and obviously you can adjust it when building your own, so it's value is not so crucial.
The other cap (labeled "???") is probably not significant either. The only writing left on it was an 'A' looking logo, and 1w9, which I don't believe denotes the value. The original is a blue, rectangular, poly film cap. This can be narrowed down through simple substitution, I'm sure.
As for the circuit itself, it's obviously derivative of the RunOffGroove Ruby amplifier.

It uses a JFET mentioned on the ROG ruby page, has a very similar input stage, and uses the same IC. However, the SuperBrunch makes different use of the 386. The tone and volume controls are passive, and are easily removed if desired. In that way, the circuit is good for on-board use, since it has a low parts count and can be boiled down to one control.
Any questions or corrections to the schematic are welcomed. Thanks for looking.
