From the vendor

Also available in horizontal format if you like that kind of thing. Boutique pedal designed to capture Neil Young's live tone in a small metal box. Ok, you'll also need a lot of tube amp wattage, and big stage and some fat riffs, but this pedal will take you a step in the right direction. This ingenious circuit combines both fuzz and overdrive to offer up a whole stack of different tone. The voltage starve control mixes things up a whole lot more. Hours of experimentation fun. 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 enclosure and vertical-mount pots. Please choose appropriate knobs. Inspired by: Crazy Horse Difficulty: Medium PCB size: 50 x 36mm Knobs required: 5 Enclosure: 1590B Download the INSTRUCTION PDF
