From the vendor

A wonderful (and very scarce) drive from a designer with quite a pedigree. Originally conceived as a DIY project for Guitar Magazine, but built commercially soon after, this beauty is described as a tonal hybrid of a Tube Screamer and a Tone Bender. That's not far off the mark. Supposedly the main dirt all over Snow Patrol's 'Eyes Open' album, which is no bad thing. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. The original only had a two-position Tone Shift control, whereas this kit has a three-position. If you want to limit your options add a note at checkout and we'll give you a different toggle switch, but really - don't! 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. Please choose appropriate knobs.
