Box of Krunch

More Marshall-in-a-Box fun, and this one doesn't disappoint.

Does what most of these kind of circuits do - give you the oomph of a fully cranked tube head. We've added some extras to this one though:

• Presence pot - an internal trimmer on the original, now an optional (and very worthwhile) external pot. Highly recommended.
• Clipping selection - added an optional board-mounted toggle switch and a couple of extra diode spots for alternatives to the stock LED clipping. Go nuts!

We've also designed the board with Mark M's slightly modified tone control, but you can easily go back to stock with a single jumper wire.

Please take note of the different box layouts. If you want a 3-knob version with centralised tone control you can only have this with wired pots. Please add a note when ordering if this is the case style you'd prefer.

Clipping pack includes toggle switch, SIL sockets and a selection of extra diodes - 2x1N34A, 3x1N4148, 2xBAT46, 2x blue LEDs

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.
