Fuzz Pedal Simulation

In case you need a transistor-level simulation of the original fuzz pedal, used by the Rolling Stones on Satisfaction, I have you covered: https://grwhitehead.github.io/us3213181/

The challenge was finding/building an accurate, sufficiently leaky, germanium transistor model to make the simulation work.

The breakthrough was discovering this paper by B. Holmes, M. Holters, M. van Walstijn. “Comparison of Germanium Bipolar Junction Transistor Models for Real-Time Circuit Simulation” https://grwhitehead.github.io/germaniumbjts/

Also, thanks to Henrik Forstén for figuring out how to process digitized audio samples through SPICE https://github.com/grwhitehead/spice-audio-tools

Hey, the latest episode of @thatpedalshow visits Macari's in London with @jhspedals to talk fuzz pedal history (with a nod to the Maestro Fuzz Tone, based on the circuit from this patent) https://youtu.be/UrJDtSolEI0

While I'm at it, here's @jhspedals on the history of distortion, including the Maestro Fuzz Tone https://youtu.be/XTGmfsKHcXo

And here's @jhspedals with the original Maestro Fuzz Tone demo record, trying to sell it as a way to make horn sounds https://youtu.be/iK4hBbVOnHQ
