From the vendor

Super-simple boost/OD box. Single bias control will take you from clean boost to overdrive, and can crank enough juice out to really push an amp into new territory. Highly pick-responsive. A great addition to any set up. Kit is available with a standard sized 1590B enclosure with battery, or a mini 1590A (36 x 90mm) enclosure with DC power only, though be aware that you'll be wiring in a very confined space. 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, in 1590B. Battery will not fit 1590A. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs.
