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.

Christine Oscillating Fuzz

Here's a fun noisemaker for Fuzz Friday. It's an oscillating fuzz built around a CD4049UBE hex inverter and has good range of noisy fuzz tones on tap. Schematic in here. Read that a B100k works better for the Frequency pot and an A20k works better for the Starve pot. YMMV


  1. verified, very cool and funny device!Thanks for lay

  2. I just built this as a synth module. Cd4049s are very have to respond to CV.
