From the vendor
Massive Marshall in a Box sound from a pretty small circuit.
This FET-based beast will get you a huge range of Marshall-style tones, from the pleasing break-up of an 18W through to the classic rock crunch of a JTM45.
The board-mounted toggle switch will give you a bass-boost, so even at lower volumes you can create some serious bottom-end punch.
Available with through hole FETs, or save yourself a few quid if you're confident enough to tackle fiddly SMT parts.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.
You will need a multimeter to tune this circuit. You *could* do it by ear but it's not recommended.
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.
Inspired by: Plexi Drive
Difficulty: Medium
PCB size: 50 x 40mm
Knobs required: 3
Enclosure: 1590B
Power and Signal pads match the Direct Connect 3PDT Daughterboard
Check Specials for powder-coated enclosure availability.
