Filth Fack - board-mount version

From the vendor

Now available with silicon transistors in place of the usual germanium for a different flavour of fuzz and more temperature stability. The 2022 version of the PCB adds extra transistor pads to accommodate ECB pinout germaniums - handy!

Take a Fuzz Face, mess around on the bench, add some pots and a sprinkling of crazy dust and you have this beast.

Classic, noisy five-knobbed fuzz box with stability, compression, gate, drive and volume controls. The fuzz comes from a pair of specially selected germanium cans which can produce tame, soothing fuzz tones or veer off into wild oscillations and gated madness with the twist of a knob or two.

Pot spacing is 21mm, so please take that into account when choosing knobs.

If you want to go all-out you can wire up a toggle switch to turn it into a Fat Filthy Fack. It's only three offboard wires. The toggle switch has to mount on the top edge of the box (along from the DC socket) if you're opting for a predrilled enclosure.

If you want the PCB without parts there's a link for that at the bottom of the page.
