From the vendor
Clone of a famous Marshall-in-a-Box pedal. Dial up some crazy high-gain crank in a very small package. Very similar to the Pink Plexi, only this one is tweaked to emulate a Marshall Silver Jubilee. 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs. Inspired by: Jubilee Difficulty: Easy PCB size: 50 x 20mm Knobs required: 3 Enclosure: 1590B Direct-Connect compatible (4-way) If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability. Download theINSTRUCTION PDF
