From the vendor

A now discontinued boutique take on the fantastic Foxx Tone Machine. Meaty fuzz tones with a selectable octave-up mode for piercing, in-your-face fuzz fun. Responds nicely to guitar volume changes, and with the Fat/Bright mode toggle switch you get two completely different sounding pedals in one. With the fuzz wound back and the guitar vol knocked back a touch this gets you some excellent QOTSA tone. With eveything turned up and the octave on you'll be spitting out leads that'll cut through anything. Twin PCB set-up for super-simple construction with minimal offboard wiring (6 wires, to be precise). The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Footswiches and LEDs mount on a separate daughterboard which connects to the main circuit with a short 6-way ribbon cable (supplied). If you want the PCB without parts there's a link for that at the bottom of the page. Partial kit: PCBs, all board-mounted components (not footswitches), 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. Please choose appropriate knobs. Inspired by: Ultimate Octave Difficulty: Medium PCB size: 82 x 50mm / 82 x 22mm Knobs required: 3 Enclosure: 1590BB Download the INSTRUCTION PDF
