From the vendor

NEW! - Now available in two flavours, JTM45 and '59 Bassman. There's no doubt about it - the Rock Box is an awesome slab of Marshall grunt, but not everyone is a fan of horizontal format boxes and multiple footswitches. Do you need that boost? No? Well here's the distortion side of the Rock Box on its own in a more friendly vertical enclosure. All the fun of the original Rock Box but boostless. That about covers it. 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 only available 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. Pre-built option is only available with vertical-mount pots. Don't forget your knobs. Inspired by: Box of Rock / 59 Sound Difficulty: Medium PCB size: 50 x 30mm Knobs required: 3 Enclosure: 1590B Direct-Connect compatible (4-way) Download the INSTRUCTION PDF
