From the post

For Fuzz Friday here's DeadAstronaut's take on the good ol' Big Muff. It features a toggle switch (Fat/Thin) that changes the output capacitor from the first stage, and a rotary switch (mode) that changes the sound type. In the designer's own words:

It's basically a classic big muff with fat/thin switching, plus 3 other modes for synthy, buzzy, octavey, duck and swell type sounds...by switching diodes and collector resistors. Rather like a bias control on a fuzz face...but for both collectors.

Here's the schematic for reference.
