From the vendor

Recreating the 80's Tube Screamer rival from Korg. Similar kind of feel to a TS, but less of a midrange hump. Same tube-like warmth and touch response. Reverse log gain pot seems to work much better than the linear of the original. 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs. Inspired by: Korg OVD-1 Difficulty: Medium PCB size: 50 x 31mm Knobs required: 3 Enclosure: 1590B Direct-Connect compatible (4-way) Download the INSTRUCTION PDF
