Having done the TS layout I thought I’d do another classic as well. Here are layouts for both germanium and silicon versions of the Fuzz Face, both based on schematics from generalguitargadgets. I didn’t go into any details about what transistors to use since this information is readily available just about anywhere else.

Update (15.10.2011): The silicon variant is now verified, thanks to Hookey.

Update (04.11.2011): The germanium variant is now also verified, thanks to Glenn.

  1. Hi,
    newbie here, I had a question about the c3 capacitor on the silicon layout, what type should I use

  2. hello everyone, a query on the fuzz face silicon project, terminal 1 of the volume potentiometer where it connects to the circuit board?

  3. Hi, John
    This means lug #2 on the volume pot is your circuit output. Now check out the wiring diagrams under “Help->Wiring”

  4. Hello,
    Newbie question, it says Volume 2 -> Output where is that? On the foot-switch?

  5. Hi there, I built this using BC108 transistors and I find them to have too much gain they feedback and squeal uncontrollably the hfe gain readings on the BC108s I have are in the 300s is there any recommended transistors I could find that are in the 100 range? Would they sound better with this circuit? Or does it even matter? Thanks

  6. It’s on the GGG schematics as “optional”. It’s really just a smoothing cap to reduce noise from the power source, and a polarity protection diode that prevents other stuff from blowing up should you ever give it power of the opposite polarity. Neither should affect the sound of the effect at all apart from the smoothing cap perhaps reducing noise a bit. Feel free to leave thme both out if you’d like.

  7. Harold, what’s the matter about that 100uf polarised capacitor on C6?

    It’s just to know, assumed that it doesn’t appear in the General guitar Gadget schematic nor in the traditional Arbiter Fuzz Face… 🙂

  8. Thanks Andrea 🙂
    Putting the trim pot on the outside of the box as a regular know is pretty straight forward. Here’s what you need to do:
    – Remove/omit VR1 from the circuit and instead get a regular 10k linear pot.
    – Run wires from the ‘e’ and ‘f’ rows next to where VR1 used to be to the center lug and one of the outside lugs on the new pot.

  9. Congratulations, Harold! Your website is an absolute goldmine 🙂

    A small newbie question: how to wire the trimpot as an external BIAS pot? And then, any of the pot lugs should be wired together?

    Thanks for your kind answer! 🙂

  10. Hi Harold I built the Germanium Fuzz, works great. I love the bass that comes off this. I dont have matched pnp’s just some
    old germanium’s laying around, but i guess thats whats the trimpot is for, thanks again.
