From the vendor
Now this is a fun little fuzz box.
At the heart of the design is the Jordan Bosstone, so that's a good start.
Then things get crazy. The extra controls give you a massive range of fuzz tones, including brass-like honking and trumpeting skronk. At extreme settings you can get some nice controlled oscillation going on too.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.
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.
Builds are only available with full kits including enclosures and vertical-mount pots. Please choose appropriate knobs.
Inspired by: Trombetta Mini-Bone
Difficulty: Easy
PCB size: 50 x 40mm
