D*A*M Meathead Deluxe

Here's yet another Fuzz Face circuit as they say. This is basically the one-knob Meathead with a Filter control that pans between 2 different input caps, and an Attack control which is the standard Fuzz control on a Fuzz Face. Good sounding silicon fuzz.


  1. Hey buddy! You can tag this one! It's been a while since I verify one of your layouts, so here we go!

  2. Josh Homme in a box :-D
    Great fuzz: Attack knob is redundant hahaha

  3. Are you shure the Trimmer is 22k? I tried to simulate the schematic but it does'mt seem to work. If you place a 2.2k resistor instead of the 22k trimmer the magic seems to happen

    1. Yes. A 20k trimmer is best. You can dial in 2.2k on it. But Fuzz Face variants are notoriously inconsistent in biasing Q2. That's why so many have a trimmer here. 2.2k may work in a simulation, but when you're dealing with the actual components things can be slightly different. Feel free to replace the trimmer with a fixed value, but use sockets or bread board the circuit first before committing it all to solder.

  4. Any idea where I can find a schematic for the Deluxe?
