DIY Projects

Note that these projects are not kits, and they do not come with step-by-step instructions. If you’ve never built a pedal before, this may not be the place to start. But they are by no means difficult or complicated as compared to other similar offerings from other sites.

Design Rules

I used the following design rules in all of these projects:

  • 1590B enclosure
  • Top-mounted DC jacks
  • PCB-mounted pots and switches
  • PCB-mounted LED with onboard current-limiting resistor and switch pad
  • Wire connection pads grouped together at the bottom of the board (except 9v, at the top)
  • No battery

There’s still flexibility: you don’t have to PCB-mount the pots, you don’t have to use a 1590B, you can run the LED wires wherever you want, and if you use a bigger enclosure you can certainly fit a battery. But all the provided documentation and drilling templates will be based on the design rules above.


Terms and Usage

No direct support is offered for these PCBs beyond the provided documentation. It is assumed that you have at least some experience building pedals before starting one of these. Replacements and refunds will not be offered unless it can be shown that the circuit or documentation are in error. I have in good faith tested all of these circuits, though I have not necessarily tested every listed mod or variation and these are offered only as suggestions. (If you have issues with your build, you can more than likely get help from some of the friendly people at DIYStompboxes.com.)

Projects may be used for commercial endeavors in any quantity unless specifically noted. No bulk pricing or discounting is offered. No attribution is necessary, though a link back is always greatly appreciated. The only usage restrictions are that 1) you cannot resell the PCB as part of a kit, and (2) you cannot “goop” the circuit, scratch off the screenprint, or otherwise obfuscate the circuit to disguise its source. (In other words: you don’t have to go out of your way to advertise the fact that you use these PCBs, but please don’t go out of your way to hide it.)
