  1. Thanks for your great work in tracing out this circuit!
    I’m doing a soulfood repair right now. i’m thinking the charge pump is bad…could let me know what +V2 and -V are supposed to be?

    • Off the top of my head, I don’t remember. If you look at some threads on diystompboxes, you might be able to find one where the correct voltages were posted for a klone build. They should be about the same for the SF.

  2. Great schematic. Using it to sleuth out problems on a non-functioning bass soul food (fried -V regulator) which appears to be nearly the same schematic-wise, although from the pics I see it has a totally different pcb layout. One thing I did notice, I believe C17 is incorrectly shown going between -V and +V2. On mine it is between -V and gnd. I believe it is a HF bypass cap for -V on U2 which it is near, at least on the bass SF.

    • I don’t have the SF on hand to double check, but I did notice something weird going on around C17. I think there was a hidden layer sandwiched between the top and bottom layers of the PCB making some connection that wasn’t there in the real Klon circuit. Maybe they made it more like the real thing in the bass version.
