Oh my. If ever there was an essential
addition to a rig then the Fuzz Face
surely is it. A bit of fiddling will get
you anywhere from creamy
smoothness to ear-splitting youch
with the right/wrong selection of
those all-important transistors sitting
at Q1 and Q2. Biasing is key!
The schematic above shows the original PNP - Positive-Ground layout,
which is also how the PCB is designed. What does that mean? Well,
basically it means it won’t play nicely with ‘normal’ pedals if you try to
daisy chain them on the same power supply. Don’t do it. The world will
implode and we’ll all look at you.
It’s perfectly simple to make a NPN - Negative-Ground version. Use NPN
transistors, flip the orientation/polarity of C1 and C2, then follow the
appropriate wiring diagram later in these instructions. The -9V connection
9v.
Probably sounds more complicated than it actually is.
