From the post
Laying out Big Muff variations never gets old for me. This one uses germanium transistors in the two clipping stages (and predates the EQD Hoof which also uses germanium transistors) along with schottky diodes (1N6263s). Q4 is a FS25444, but the usual BMP transistor suspects will work as well (2N5088, MPSA18, BC549C, etc). Other than component values, the biggest difference between this and a typical Muff is the placement of the tone section. On a typical BMP the tone section is immediately following the 2nd clipping stage, followed by a gain recovery stage. Here, the gain recovery stage follows the 2nd clipping stage, pushing the tone stack. Schematic can be found over on FSB.
The bass version, the Bassweet, can also be built on this board with just a few value changes. The Gain and Tone pots are changed to A10k, and the rest of the value changes are illustrated below:
