Hope everyone's having a safe and healthy Fuzz Friday. Found out the Black Ash had been traced and figured I'd draw up a layout. I figured it was a pretty straight Tone Bender Mk II clone, and it is with a simple tone control tacked on just before the volume pot. Was slightly surprised that it uses all silicon transistors. The resistors in the originals are old school carbon comps for the mojo. Here's the schematic for reference. You can probably get away with 4.7k and 47k resistors instead of the 4.6k and 46k resistors listed. Also alternatives to the 2N3903 would be 2N2222a, 2N2369, etc. Shoot for 100-150 hFE.
If you want a fabricated PCB to build on, check out the Earthbender in the store.
