Benson Amps Stonk Box Automatic Thermal Bias Fuzz
Benson Amps · pedal
The Benson Stonk Box is a germanium fuzz pedal featuring automatic thermal bias, a circuit that gently warms its 2N404 or 2N527 germanium transistors to a preset operating point using analog components, ensuring consistent tone regardless of external temperature, a real solution to germanium fuzz's classic weather-sensitivity problem. Controls include Filter, Volume, Tone, and a Trim control for fine bias adjustment, and the pedal takes 2-3 minutes after power-up to reach full, correct operating temperature and tone.
