The B%st pot is just a second volume control with the B%st stomp selecting between the two. I have shown the B%st LED connections for the switch, and to complete it you will need to connect the anode to 9V via a limiting resistor to taste.
Info about the original:
The WTF Fuzz is the fuzz for people who don’t like fuzz! Get mild OD sounds all the way to crazy random octave fuzz. You can achieve sounds similar to a trumpet or trombone as made famous by Paul Trombetta, who created this circuit for us….Thanks Paul!!
Thanks to Matt for the schematic for this Bosstone based effect.
