fOXX Tone Machine

The fOXX Tone Machine is a classic fuzz box and a very versatile octave effect as well. Pretty standard controls, and the toggle switch controls the octave effect. I've laid this out for onboard pots and octave switch, and added polarity protection and power filtering. 2N3904s or 2N2222s can also be used in place of the original 2N3565. Hope you're stocked up on 10µ caps!


  1. Fantastic job... gotta try this one out... You have considered my suggestion :)

    Man....thank you very much :)


  2. I've been trying to debug this for a few hours now, but I can't get it sounding right. I'll report back soon, I hope

  3. it turned out to be a bad diode, its verified!

  4. Hi, can i use the 1n4007 instead 4001 ? Thanks

    1. Yep. The 4001 is for polarity protection and a 4007 is a good sub.

  5. Thank you so much for this and every single layout on this site :) Verified! Sounds sick!
