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.

OMG Fuzz

Found this design over on DIYSB and thought it would be a good Fuzz Friday layout. The One Mighty Gnarly Fuzz is a pretty straight forward design that you probably have all the parts for in your parts drawer. Check out the DIYSB thread for the schematic, and build notes.


  1. mines working, im assuming its working as its suppose to. not a huge fuzz fan so they all sound awful to me lol thanks for all the hard work you do and do you think we could possibly get a few more high gain preamp/cascading jfet distortions :d

  2. Hello nice works man!! do you have any idea about one fuzz pedal that Im looking for some time. EQD - bellows. I know it uses 1 transistor and some op amp but. I dont have a starting point.
