Yet another FET boost? Yawn.... Ah, but wait. This beast of a boost boasts a big bonus. Massive clean headroom available on tap thanks to an onboard charge-pump giving 18v from your 9v supply. . Like, massive amounts of boost. More than you could possibly ever need (though its always nice to have some in reserve, right?). Sounds great? It is. But wait... there's a toggle switch! Flip that and your clean boost starts to bite, giving oomph and grit that's bordering on overdrive. Your amp won't know what's hit it. The kit is supplied with a vertical-mount pot 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: Katana Difficulty: Easy-Medium PCB size: 30 x 50mm Knobs required: 1 Enclosure: 1590B Direct-Connect compatible (4-way) Check Specials for powder-coated enclosure availability.
