Dear Builders,

Under the Projects menu you find all the PCB layouts that I have made together with their documentations.

Technical stuff

Basically I try to fit my layouts into the standard Hammond 1590B size boxes, however there might be cases where this is simply impossible for example due to the number of pots. I always mark the sizes with icons. I also try to build all my layouts, but I don’t always have the time or energy for that. I mark the verified layouts too with an icon but if you find an unverified one and build it yourself I’d highly appreciate if you could drop me a mail with the results.

Below is the legend for the used icons


Fits only the size 125B or larger


Fits only the size 1590BB or larger


Fits the size 1590A too





In the case of the average 1590B sized layouts the pots are soldered to the PCB from the solder side and they hold the PCB in place in the box. The rectangular pad is for lug 1 (figure 1).

In many cases – especially for the 1590A sized PCBs – the pots are not soldered directly to the PCB, but connected with wires. In these cases the pads are not necessarily at the same place or near each other, but are marked with the lug numbers. The lug numbering is the same as above. The markings are often abbreviated due to the lack of space, for example instead of “Volume1” only “V1”. The footswitch, the jack connectors, the LED and the power connector are never soldered directly onto the PCB, but are connected with wires. The pads are marked and the offboard wiring is done (figure 2).



Legal stuff

You can use these layouts free, except for commercial purposes. It is ok to build a pedal or two for your buddies or band mates. You may also sell the pedals that you have built – eventually everyone can get bored of the sound of a pedal. However I obviously don’t want to see my layouts in pedals running under different brands. These layouts are my artworks and my intellectual property therefore I own the copyrights. If you make a pedal for someone using my layouts please mention that you are using my layouts. That’s it about the copyright things, I think you all get the idea ;)

Also I do not provide any support regarding these projects. All the necessary info is in the documentations and here in the intro. If you still have questions just send me a mail, but I can’t guarantee that I’ll be able to answer in a timely fashion (or at all…) I also don’t take the responsibility for the quality of the projects or for any injuries, damages or harms caused by these projects. Please use common sense: the soldering iron is hot, a wire cutter or an XActo knife is sharp. The tools used are not the most hazardous things in the world, but still use them with caution.

And after this rather long intro see the goodness below, hope you will enjoy them ;)
