Breadboard fuzz. I built a fuzz circuit on a breadboard and tested its output through a guitar amp. This is the working setup, with its wires, components, and sound out in the open.

01 / Reference + simulation
A footprint-sized Bazz Fuss reference schematic. MPSA14 transistor, BAT41 collector-to-base diode, 10 kilohm collector resistor, 470 nanofarad input capacitor, 100 nanofarad output capacitor, and 100 kilohm volume potentiometer. These reference values and connections have not been verified against the photographed breadboard.
