From the vendor
Gotta love amp-in-a-box circuits when they sound as good as this... Give your amp all the crunchy goodness of a JTM45 with this box of tricks. Hugely versatile range, from light crunch to full-on chug, with the classic 3-band Marshall tone section adding more tweakability than you could wish for. Just keep an eye on Snoopy or he'll have it on his board. Vertical-mount pots are highly recommended for this build, but please note they have a round shaft - you'll need knobs with set-screw fitting. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Pot spacing is very tight (17.5mm), so you'll need small knobs. 1900H fit well. 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 was 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.
