From the vendor

Beautifully simple pedal - who doesn't love a one-knobber after all?

Think of it as kicking in the gain on your amp, so essentially a second channel. It'll give you 'more' without colouring the tone. No bells or whistles, just that extra oomph when you need it.

The original uses obsolete Schottky diodes for the clipping, but BAT41 will do the same job just as 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knob is not included.

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

Inspired by: BMF Wide Open (one-knob version)

Difficulty: Easy

PCB size: 50 x 24mm

Knobs required: 1

Enclosure: 1590B

Direct Connect compatible (4 way)

If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability.
