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.

Flying Guillotine Fuzz

For #fuzzfriday I present to you the Flying Guillotine Fuzz, designed by Freppo over on FSB. Here's what he had to say about it on his blog:

The front end, tonestack and the output stage are all borrowed from the Big Muff, but the two Muff gainstages is replaced with a discrete op amp (by Joe Davission) modified with a odd feedback transistor clipping configuration. It's a VERY loud circuit. Way louder then the loudest Big Muff I've built.

    The trimmer should be set so that the collector of Q4 is at about half voltage.

    Freppo and someone in the FSB thread mentioned the top end sounding grainy or gate-y, and I would agree. The circuit also has decent guitar-volume clean-up.
