Electronic Audio Experiments Magic Missle

 Sounds like a Devi pedal but with much more nuance in the controls. actually turns into an overdrive on lower depth settings. One of the knobs was drilled off-center and the paint is wonky.

From EAE:

This is a six-transistor silicon fuzz/drive with some unusual sounds at extreme settings. It takes some inspiration from the Escobedo/Devi Ever lineage of transistor fuzz (one of the first pedals I ever owned was a Devi Ever Hyperion), which are haphazard yet undoubtedly brilliant. A few such designs feature a PNP/NPN clipping cell which caught my attention. After some breadboarding and SPICE experimentation I discovered that it shuts off the waveform at the peak of each cycle, producing a frequency "doubling" effect unlike a rectifier-based design.

In this implementation all manner of transistor drive and fuzz tones are available - the input capacitor blend alone can tailor the character across a big range and it even does lower gain quite well. At max settings it produces a slew of unusual harmonics due to the NPN/PNP cell.
