Ripping High Gain Oldschool Fuzz
Adjustable but not refined—an angry, raw, vintage-style 2-transistor fuzz with
extra controls and tweaks to let you recreate oodles of classic fuzz
sounds with minimum hassle
The Skreddy Pedals™ BC109 FUZZ is made from
silicon transistors for power and temperature stability, but it's darkened
so you can get germanium-ish effects out of it too.
The 2 transistors are piggybacked for better tone (smoother, lower noise
than single transistors), giving this circuit 4 transistors total.
The extra controls let you emulate different classic fuzz tones from the 60's
and early 70's along with improvements for some of
the issues those early fuzzes had (noise reduction, adjustable tone, and
input impedance selector switch). Can get frazzly or smooth, bright or
This is a rude, biting fuzz that does not totally clean up with the volume knob;
at very low guitar volume it's still slightly gritty sounding. So it's
not one of those "leave on all the time" fuzzes; it's more of a "stomp for
mayhem" type of fuzz! It's not just another Fuzz Face™
clone; it's more like a fuzz on steroids.

About the name BC109 FUZZ:
It refers to the part number
of the transistors used and is certainly not a unique moniker. In fact it's
so generic it cannot be used as a trademark; that would be like claiming to
own the terms "V8" or "327" as the name of an automobile model. There are other
products already out there using "BC109" as their name or part of their name
(I know of at least 3 others, not to mention several other products named "BC108").
If you want to use the transistor part designation of your fuzz as its name
too, nobody's gonna stop ya. Or you could think up a unique name.
Either way is fine with me.
Do not share power with a daisy chain. Not because
that would fry anything, but just because this circuit is very sensitive
to ground-loop hum. In other words, it will create extra noise. It is
typical, normal negative-ground, though; no special power requirements.
9v battery is not included.
If you use a battery, then remember to un-plug the input cable from the
pedal’s input jack when not in use to prevent draining (or you can also
just plug in a power-supply, which disconnects the battery).
You may supply external power through an AC adapter.
All Skreddy Pedals accept the industry-standard 9v DC plug (5.5mm barrel x
2.1mm center coax), negative tip. Please use a quality, regulated,
filtered power supply.
