The Gimp - Filthy Fack with added OOMPH!

Who doesn't love the Filthy Fack!? Five knobs of germanium fuzz fun.

Now let's take that one step further and add a few tweaks to make it a whole lot more useful and, well... fun.

First tweak is a Girth control, which will give you a variable version of the Fat knob on the Filthy Fack. Not so noticeable when playing with normal fuzz settings, but turn the Sanity (Stab) pot down into oscillation mode and the extra frequencies running around the circuit become very apparent, totally changing the nature of the oscillations.

Next up is the Sanity bypass footswitch, giving you two completely different beasts with a single stomp of the foot. With it bypassed you're giving the circuit the full 9V of power it wants. Kick it and the Sanity pot comes into play, starving it just how you want and unleashing the beastly oscillations. For extra fun you could have this as a momentary switch - an Alpha DPDT will fit into two columns of the three-column pads - but you'll have to think about offsetting your footswitch holes when drilling to compensate.

If you go for the vertical-mount pots they have round shafts - take that into consideration when ordering knobs - you'll need set-screw fitting.

Controls are: Girth (Fatness), Grunt (Gain), Thrust (Vol), Sanity (Stability), Gag (Gate), Choke (Comp)

Partial kit: PCB, all board-mounted components (not footswitches), pots.

Looks and sounds demonic 5 product stars
"Took me about 3 hours to complete the kit, not having done a project in a few years I took my time. When I first plugged it in, I thought I had broken something as the noise level was horrendous. Once I started playing, it was just amazing. The two red LEDs look like a demon's eyes, and the sound fits. There's a massive range of sounds, and the sanity foots witch is really useful. I would highly recommend this pedal!" Noiseguy - 23/04/2016
