From the vendor
If you're a fan of signal smashing there's nothing unpleasant about this one...
Capable of some fairly 'normal' compressed fuzz tones, but it really starts to shine when you mash things up a bit. Crank up the Onset knob and flip those Gain, Crush and Treble switches to see how messed up you like it. You may be surprised.
If you want the PCB without parts there's a link for that at the bottom of the page.
Partial kit: PCB, all board-mounted components, pots.
Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.
Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.
Inspired by: Unpleasant Surprise
Difficulty: Medium
PCB size: 50 x 46mm
Knobs required: 2
Enclosure: 1590B
Direct-Connect compatible (4-way)
