Randy Sarafan made this “Fuzz of 100 Faces” guitar pedal:

For a long time I have been a fan of the Multi-Face Pedal and have been having fun exploring the different nuances of fuzz by swapping around parts on a breadboard. However, I wanted to make a more permanent fuzz pedal that I could use to toggle through different capacitors and transistors very quickly. I came up with this design, which involves 4 rotary switches. In this way, I am able to quickly achieve 1,296 rockin’ combinations. Hence, being a fuzz pedal with lots of combination, it was thus aptly named “The Fuzz of 1000 Faces.”
