Classic rock distortion inspired by the legendary tones of Zakk Wylde.

This product is the unpopulated PCB only - full assembly, soldering, and fitting in an enclosure will be required.

Classic rock distortion inspired by the legendary tones of Zakk Wylde.

Just classic, overdrive tones with tons of flexibility - a great build if you need boost, drive and distortion but you have limited space on your pedal board.

FYI: The actual PCBs are white rather than black - check out the photos for more.

Designed to fit a 1590B enclosure with 9mm pots (just remember to get ones with nuts!) and a voice switch to move between GT-OD inspired and ZW-44 voices. I wouldn't recommend these for beginners as there's some potentially fiddly soldering but all doable if you're careful. You could make things even easier by using standard, off-board potentiometers and switches and connecting them with wire.

Installing the pots and switch

The 3 potentiometers, and the voice switch, all mount on the back of the PCB ready to be fed through the holes in your enclosure. Just remember to order right-angle pots with either metal or plastic shafts but they need to have fixing nuts.

Transistor pinout

A number of different Darlington Pair transistors can be used in this circuit, as long as they're relatively high gain, and each will bring its own flavour. However, you can't always guarantee the pinout across different components so please double check before soldering.

If you have a V1 board then the transistor pinout should match this.

If you have a V2 board then the transistor pinout should match this.

Wiring the daughterboard

The 3PDT daughterboard connects to your footswitch and provides handy connectors for input, input ground, output, output ground, your main ground connection and the 4 wires leading to your board. Just remember:

Orient your 3PDT pins horizontally
Attach the PCB with the small triangles facing up when viewing the inside of your enclosure - this should match the similar triangles on the main PCB
Connect each pad to the corresponding pad on your board.
