Finally, a bit of color! This is the Ugly Face fuzz noise snarl stutter box, designed by Tim Escobedo, designer of all sorts of interesting and insane effects. I've added the popular LFO mod to add the tremelo/auto-filter type sounds you hear in the demo below.
Knobs (clockwise from the top left) control noise, gate, volume, frequency, and LFO speed. The switch changes the LFO shape.
What can I say...this thing is insane. If you need to simulate a jet taking off then use this. Every scream and squelch and buzz is exactly what I wanted from this pedal, and more. Very happy with this build. Also happy with the way the enclosure came out. The ugly face on the front is Hedorah, the villain of probably the best Godzilla movie, and the only one I remember watching with a psychedelic freak-out mid movie.
