This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Rotary Capacitor Switch
The input caps on some old circuits like the Fuzz Face, Tone Bender, or Rangemaster are ripe for variation. Here's a board that will allow you to switch between 6 different capacitors of your choice. You could also use this for a Gibson Varitone-like switch on a guitar. As with the Rotary Clipping Switch layout, use a 26mm enclosed 2 pole 6 position PC mount rotary switch (preferably from Alpha as their datasheet is what I used to layout the switch pads), mounted from the component side.
