As I was digging through piles of handwritten notes – some written on both sides of a sheet of paper, many without description what the actual schematic did – to find a starting point for a schematic, I decided to make a serious effort to retain documented schematics for posterity.

From a Google search, I found the free software DIY Layout Creator (, which turned out to work really well. Apparently, it is a favorite among stompbox builders. (Note that on MacOS X , you get a random error message trying to run it, and you have to allow running apps downloaded from “Anywhere” in order for it to work.)

Here is the schematic for #61, which is an HSH guitar with two three-position mini toggles that switch the humbuckers into series/parallel/split (outer coil) mode, and combines the humbuckers with the middle pickup in position 2 and 4 of a 5-way blade switch.




And the link to the DIYLC project file. Feel free to enhance, correct, and share.
