From the vendor

A signature drive that really delivers. The front end of the circuit is basically the Spooky Mids active mid-frequency pre-amp, offering a huge range of mid-range sonic sculpting. This pushes a sweet high gain FET distortion, giving you some fat, responsive tube-amp style drive. It sounds big. Really big. Even at low volumes. An onboard charge pump gives you fat 18V headroom from your standard 9V supply. The FETs need to be biased correctly, so you should really have a multimeter to hand if you're going to build this. It's designed for tiny, fiddly 3mm resistors, but we can supply 6mm if you want to save your eyesight and don't mind mounting them vertically. We also offer either through-hole or SMT FETs, depending on your confidence with fiddliness. Pot spacing is 17.5mm - take that into consideration when choosing knobs. The pots 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: PCBs, all board-mounted components depending on selected options (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 enclosure and vertical-mount pots. Please choose appropriate knobs. Inspired by: PG-14 Difficulty: Hard PCB size: 55 x 50mm Knobs required: 6 Enclosure: 1590B Check Specials for powder-coated enclosure availability. Download the INSTRUCTION PDF
