From the vendor

There are many pedals out there that try to recreate the tone of a Marshall amp, and lots of them do it well. This is one of them.

Relying on op-amp ooomph rather than the FET gain stages of many others, this is a simpler build with no biasing to worry about. It still packs a punch regardless.

Where this bad lad does shine is the three-band tone stack. Very useful. Cut those mids and chug 'til Tuesday.

Five knobs of fun with an optional clipping selection switch to add a touch more versatility.

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 as 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.
