Clone of the MXR Distortion+, the 70's workhorse of the rich and famous (well, Randy Rhodes apparently). A few component changes and you have an OD250. Nice.
Great little distortion in stock format, but why not play around with the tone? Clipping diodes make all the difference here, and this new version of the PCB includesextra spots for an optional second set and a switch to go between them.
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 only available with full kits, and will take a battery. Knobs are not included.
Builds are only available with full kits including enclosure. Please choose appropriate knobs.
PCB size: 50 x 20mm
Knobs required: 2
