NPN Silicon Fuzz Face

Postby maz » April 11th, 2014, 12:31 am

The Fuzz Face, first issued in 1966 by Arbiter Electronics Ltd, is probably the most famous fuzz used by many guitarists like Jimi Hendrix, David Gilmour, Jack White from The White Stripes, Dan Auerbach from The Black Keys and many more. It was only in 1993 that Dunlop Manufacturing took over the production, making a variety of Fuzz Faces to this day. Some germanium and others using silicon transistors for more stability.

But over time the circuit has never really changed, simple but still very effective, this "eleven parts" thing (including pots) makes all the amazing sounds of this pedal, which makes it a "must-see" for any DIYers wishing to build his own DIY fuzz face.

Here is a proposed schematic of the Silicon NPN version, you can experiment with any NPN transistors at different HFE.


All together, bigger we can be!
