From the vendor

This is a dual circuit box of awesome blues and Nashville tone on tap. The GREEN channel (right) is essentially a Nobels ODR-1 with some small tweaks. We've added the option to build this with the parts for the untweaked circuit which has more gain, but the makers of the dual pedal thought less was more. Another option is to make this channel a four-knobber with an added bass control. The ODR-1 is notoriously bottom-heavy, so this is a nice mod (thanks AionFX). The BLUE channel (left) is based on a Blues Breaker, once again tweaked a bit to the builder's taste including upping the output level, which is nice. Both sides are individually switched, and this thing really sings when both channels are engaged, with the ODR-1 pushing the BB. Lots of components on the green side, so it's been designed for 3mm resistors. You'll need your best specs on to read the colour codes. The boards have been designed with the dual pedal in mind, so there's not too much wiring to be done. The main PCBs connect to the footswitch daugherboards with header pins to keep things neat. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Supplied in a 1590BBS enclosure (if you select it), which has the same footprint as a 1590BB but is slightly taller. Lumberg jacks on this one rather than Neutrik. If you'd rather build the individual channels there are links to those kits below. 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.
