ETI Fuzz Struzz (a.k.a. Guitar Effects Unit)

There was a mistake on the layout, that's now fixed. This calls for both +9V and -9V supply. Use of inverter pump daughter board is recommended.

The GEU is good sounding octave fuzz, with an optional mode of just fuzz. The fuzz is a fully rectified signal and is quite chewy. For some the Fuzz alone might not be loud enough, this can be fixed by raising the value of the 820 ohm resistor and lowering the 39k one. Or one could just replace both with a normal volume pot for a more standard approach. The "struzz" is the fuzz with an octave higher signal mixed in. Good for singal notes and leads.
