From the post
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!
