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.
