Toxic Minx - Distortion+/OD250

Clone of the MXR Distortion+, the 70's workhorse of the rich and famous (well, Randy Rhodes apparently). A few component changes and you have an OD250. Nice.

Great little distortion in stock format, but why not play around with the tone? Clipping diodes make all the difference here, and this new version of the PCB includesextra spots for an optional second set and a switch to go between them.

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 only available with full kits, and will take a battery. Knobs are not included.

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

Difficulty: Easy

PCB size: 50 x 20mm

Knobs required: 2

Enclosure: 1590B

Direct-Connect compatible (4-way)

Excellent and versatile 5 product stars
"Great overdrive with both controls at noon. More gain (and treble) as you crank things up. Leave the gain low, crank the volume, and this pedal works as a lead boost in your effects loop. Really simple, effective two knobbed box of wonder." Ian - 20/12/2018
Very good 5 product stars
"This pedal, once built, is very good. Very good indeed. I lost a few hours today just riffing out some old shit I've been playing for years, it throws you back to the 70s and makes you sound ace. Easy build, brilliant sound. This is a definite keeper." TGGD - 13/05/2014
Toxic Minx 5 product stars
"my first kit from Pedal Parts, nice simple kit, took about an hour to solder the board and test, then another hour to wire up the switch. Great distortion sound, works best turned up to 10 :)" Cosmic Jim - 05/03/2014
Old school dirt box 5 product stars
"Very easy kit to build and has that gritty fuzz box feel to it that takes you back to your first pedals. It goes from a clean mild OD pretty much straight to an all out fuzz-dirt. Swapping diodes makes the world of difference, even lifting them gives a super hairy boost. Modding it for more bass improves it a bit. I keep saying fuzz, which it isnt, but don't expect articulate distortion out of this. It nails 70's rock and is ok as a standalone dirt but much better just boosting an already dirty amp."
