Skreddy Screwdriver

Here's a thing I've been meaning to try out for a while. A Skreddy Screwdriver. I did this on an old Madbean Cosmopolitan board. As you can see, the Screwdriver combines a MOSFET input driving a silicon BC109 driving a germanium AC130. Very interesting topology. The MOSFET overcomes the typical impedance issues with fuzz pedals, the silicon stage gives it a stable driver and then the final stage is the germanium, "tone" transistor.
