From the vendor

Now discontinued Japanese boutique take on emulating a cranked 70s era Marshall.

We're wondering why production was stopped, as it does a fine job in its endeavours.

The original is a three-knob unit, with an internal trimmer for a 'Weight' control. We've added an extra pot space so you can have this external, but honestly - it's likely you'll set-and-forget, so stick with Tone, Vol and Gain is our shout.

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 will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.

Inspired by: Vemuran Karen
