From the vendor
Silly name. Serious fuzz. Nail the classic tone of Dave G's solo from "Time", with all the tweaking you could possibly desire across five knobs. As well as the obvious Volume and Fuzz pots this box also gives you: • Body - how much bass you're pushing into the circuit - has a huge bearing on the nature of the fuzz rather than just the frequency range • Brite - as it says, brighten up the tone. Huge range from dark and murky to brilliant • Range - choose how much gain you want the first fuzzy transistor to have, which has a knock-on effect on the rest of the circuit. It's a beast, but it can also be a pussycat with the right settings. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Spacing is tight (17.5mm apart), so you'll need small knobs. Note: The PCB layout has been slightly revised compared to the images in the document. The BOM is identical. 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. Please choose appropriate knobs. Inspired by: Lunar Module Difficulty: Medium PCB size: 50 x 36mm Knobs required: 5 Enclosure: 1590B Direct Connect compatible (4-way) Download the INSTRUCTION PDF
