From the vendor
What could be better than a sweet old DOD OD250? Perhaps a super-tuned box of just that with bells on. This circuit gives you all the feel of that classic, but with a metric shed-load of extra bottom end and a very useful three-band EQ to shape that earth-shattering signal to perfection. This is heavy. Like, proper heavy. Just to make things even sweeter we've added the option for extra clipping on a toggle switch, or you can even drop the clipping altogether for a massive box of crunch. The latter is especially useful for you bass fiends. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Pot spacing is 17.5mm so small knobs are a must. 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 (depending on selected options), 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 and vertical-mount pots. Please choose appropriate knobs.
