R1 and R4 are optional pulldown
resistors, D1 is power supply
polarity protection. All three are
optional.
Schematic above is for NPN / negative
ground version, based on the Range
Blaster modifications at Fuzz Central.
The original used PNP / positive
ground supply.
To convert for PNP, simply reverse the
orientation of D1, C2, C3, and hook up
the power in reverse as shown on the
PNP wiring page further on.
Original used OC44 transistor, but
good luck! There are lots of
germaniums suitable for this circuit,
and all will give their own unique
character. Dig around and find your
ideal sound.
