From the vendor

This is one half of a rather nice dual blues/Nashville pedal. We've designed the PCBs so you can build the two sides of that pedal as stand alone single units, or easily combine them in a bigger box. See links below for the sister circuit and the combo kit. This is the BLUE channel of that lovely box of tones. Essentially a Blues Breaker with some small tweaks, including more output - a worthy modification. 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. Builds are only available with full kits including enclosures. Please choose appropriate knobs.
