Skreddy Pedals BC109
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).
This can be a rude, biting fuzz or a creamy-sounding fuzz or a fizzy, nasty velcro fuzz, depending on how you set it up. If you want good guitar-volume clean up, turn the bias up high. If you want 60's style mayhem, turn it down low.
No special power requirements, just regular negative ground 9v.
To get lower-gain, overdrivey sounds (like some germanium-equipped fuzzes), just set the impedance selector to "HB".
Volume stays at unity gain, around noon, more or less, depending on the bias setting, which will interact with and require adjustments to the volume.
Fuzz stays either at max or backed down just a hair. Your guitar volume will go from all-out fuzz at 10 to distortion at 9, heavy overdrive at 8, and all the way clean down at 3 or so.
These settings were worked out using a Stratocaster guitar.
Clock settings: 5:00 = max, 7:00 = min
Obviously your mileage may vary; just think of these as starting points...

*These names are just used for comparison purposes; no artists have endorsed this product, and Skreddy Pedals does not own the names "Fuzz Face" or "Tone Bender."
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.
