Benson Amps Stonk BOX
Benson Amps · pedal
The Benson Amps Stonk Box is a germanium MK1 Fuzz with an automatic thermal bias system that keeps the germanium transistors (2N404 or 2N527) at a consistent operating temperature using analog warmers, eliminating the temperature sensitivity of vintage germanium fuzz. Derived from the very first fuzz circuit ever made, it retains the original Filter and Volume controls and adds Tone and Trim for an expanded palette. The Filter control manipulates both gain and bias point simultaneously, creating a dynamic expander effect at low settings. Buffer and pedal-order agnostic. Handmade by Benson Amps in Portland, Oregon. Regarded as a breakthrough in temperature-stable vintage germanium fuzz design.
What stands out
“Automatic thermal bias germanium MK1 Fuzz that delivers consistent vintage germanium character regardless of stage temperature, solving the classic consistency problem of vintage germanium transistors”
— from the community notes
“Used for blues-rock, classic rock, and psych applications where vintage germanium fuzz character is wanted”
— from the community notes
“At standard bias with Filter at minimum, single notes can lose sustain and become percussively gated, which is a deliberate circuit characteristic”
— from the community notes
“The automatic thermal regulation is the standout breakthrough -- decades of players waiting for a reliable, temperature-stable MK1 fuzz”
— from the community notes
“A genuinely important pedal for germanium fuzz enthusiasts”
