From the vendor

Highly-hyped, highly priced Dumble-in-a-box. Is it good? Yes, its good. Is it original? Well, no. Unless tweaking a Tube Screamer can be considered original. No wonder there's so much goop on them. It's a very responsive overdrive, and considering the TS architecture it's remarkably un-TS-like. Huge gain range, from a touch of drive to full-on oomph, and the tone shaping is very tweakable with the addition of the 'Accent' pot. Now with its own dedicated PCB designed for vertical-mount pots, though you can wire up normal ones if you prefer. Includes a spot for the extra cap required for the Jazz/Rock switch, though you'll have to buy the switch seperately and drill the hole yourself. 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.
