WampPlus

From the vendor

The MXR Distortion+ - a classic that needs no improvement. Wait... EVERYTHING can be made betterer, surely.

Cue Brian Wampler, an electron wizard behind many magnificent creations. In a Premier Guitar article back in 2008 he outlined his suggested mods of this sonic stalwart.

Treble roll-off tone control (very subtle, but useful), improved gain, and switches for compression, clipping and bass mods make this a tweaker's toolbox of tone.

Brian suggested germanium diodes in the clipping sections, but these are getting crazy rare. We've substituted them with BAT46 which have almost identical clipping qualities.

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 (depending on selected options), 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.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
