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 dark.
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.
