Not quite a Fuzz Friday, but a Filter Friday I guess. Goes hand in hand with some fluff though. The Sound Saw has two different passive filters that are selected by the channel footswitch. The filters then share a recovery stage with 2 transistor gains. Here is the schematic for reference. You can use a common cathode LED for the channel switch or 2 individual LEDs if you prefer. See wiring diagram below. Lay this out for a 125B but should be light enough to adjust for 1590BB if you prefer. Will probably make a fabricated version of this in the near future too.
