From the vendor
NEW FOR 2022 - updated version with Chuck D. Bones' mods to make this function like a production pedal should. No more squeal with the treble right up, and better tone/volume controls. Drive pedal to get you the sweet grunt and growl flavour of an Orange amp. Gutteral lows and screaming highs, thanks to the frequency boosting, rather than cutting, tone section. All this tone shaping happens before the main grunt is applied, which makes it all feel.... different. Wonderfully open-sounding and articulate, and should give oomph to even the wimpiest amp. The PCB has been designed to take both through-hole and SMT FETs as the former are getting harder to source. Only go for the latter if you're a solder ninja. 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 enclosures and vertical-mount pots. Please choose appropriate knobs.
