Benson Amps Germanium Fuzz
The Germanium Fuzz is a fuzz pedal. The knobs change the sounds. It will take 2-3 minutes on average to sound correct after plugging it into power. The color of the LED indicator light might change.  Don’t turn the internal trimmer. This pedal is designed around two germanium 2N527 OR 2N404 Germanium Transistors.  They have been graded for gain and leakage and carefully matched to sound their best.  They are set up in the ubiquitous 60’s circular fuzz topology, and tuned for good sound, and include some additional oddities aimed at solving the issues that prevent more widespread use of Germanium devices.
