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.

Here's another overdrive from Lovepedal, the Kalamazoo. Somewhat similar to the Timmy/OD11 but with different tone controls. D5 on originals is a 1N914/4148 (they're pretty much the same diode), but a 1N5817 or even a 4001 would probably bet better (it's for polarity protection). Also, I've included pads for the capacitor labeled "Cx" on the layout. Some find adding a 820pF capacitor there helps improve the sound, but if that value cuts too much high end, try something in the 47-470pF range.
