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.

Blackout Effectors Fix'd Fuzz Deluxe

For #FuzzFriday, here's the Fix'd Fuzz from Blackout Effectors. Part Big Muff, part Bazz Fuss, part Fuzz Face, the Fix'd Fuzz uses the basic structure of the Big Muff, but replaces the 2 gain stages with a Bazz Fuss and a Fuzz Face-esque circuit. What makes it really interesting is that every stage of the circuit is switchable. This allows it to be anything from a boost to a full on fuzz machine of doom. The original version had the switching, but 2 of the controls as trimmers internally. The deluxe version, which is laid out below, has all control externally for maximum tweak-ability. Here's a schematic for reference.




Since all the switching can be confusing, here's wiring diagram for all those DPDTs.

  2. I had to change the 3.9K resistor connected to Q1 to 390r and the 47k resistor to 10K to get the boost circuit working. Everything else works and sounds great.

  3. Beginner here. Is it possible to build using just the Fuzz 2 and filter/output part of the circuit? Just having the sputter buzz scuzz fuzz would be ideal for me. Tried in store and loved the pedal, but would change a couple things to suit my needs.
