The fuzz face was one of the first pedals ever. Designed on the late 60s it has been used by many artists and for sure made famous by Jimi Hendrix.
Today’s project is a Silicon version of the fuzz face circuit, designed to operate with NPN transistors and +9 volts.
This is one of those circuits where you can feel free to experiment with different alternative values and transistors (Remember to check the pinout of them!). Back in the day most of guitar electronics where done with whatever they had available, that’s why is pretty common to find a lot of variations on the values for a same circuit.
We have included a polarity protection diode, to make sure nothing bad happens to your build if by mistake it’s plugged in the wrong power supply. We have also included the status LED on board, to keep your build tidy.
