A variety of fuzz sounds!
The Silicon Fuzz is equipped with a circuit voltage control (VARIAC) that controls the drive voltage, which can be adjusted from 5 to 15 volts.
This not only makes it easy to produce the unique fuzz tone that occurs when the power supply voltage drops (battery depletion), but also makes it possible to produce a transparent fuzz tone by setting the voltage higher.
Power supply 9V: 006P/9V dry battery or 9V AC/DC adapter
