Benson Amps Germanium Fuzz (Studio Black) Product Details Color: Studio Black Brand: Benson MPN: Germanium Fuzz UPC: 860044002466 EAN: 0860044002466 Brand: Benson Style: Overdrive Color: Studio Black Voltage: 9 Volts Signal Format: Analog Item Weight: 15.1 ounces Package Dimensions: 5.51 x 4.13 x 2.6 inches Item model number: Germanium Fuzz Date First Available: April 18, 2023 Color Name: Studio Black Signal Format: Analog Voltage: 9 Volts This pedal is designed around two germanium 2N527 OR 2N404 Germanium Transistors. They are set up in the ubiquitous 60's circular fuzz topology, and tuned for good sound. The bias of the transistors in this pedal is automatically regulated by a circuit that GENTLY warms the transistors to a preset operating point. The circuit has been tuned to be used as a rich sounding clean boost, an overdrive, all the way up to an aggressive fuzz with some octave overtones. 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....detailed below. THE FIRST FUZZ PEDAL WITH AUTOMATIC THERMAL BIAS TECHNOLOGY The bias of the transistors in this pedal is automatically regulated by a circuit that GENTLY warms the transistors to a preset operating point using analog components, and ensures a consistent sound, no matter the external temperature. When the LED is orange, the transistors are warming up to increase their hFE (transistor gain) and to shift the bias point to the correct voltage. When the LED turns green, the warmer is off because the correct bias and hFE have been set. Expect the LED to toggle back and forth every so often while the pedal is on... that is how you know its working. The heaters will warm the transistors enough to still be effective on a sunny stage, but far cooler than anything that would harm the transistors. This pedal is designed to operate between freezing and 100F but might still sound outside this range. There are two colors: Studio Black is not meant for direct sunlight, Solar White is new with it. We have found there is a 20F difference between a black pedal and a white pedal in direct sunlight. Payment Back to Top We accept Paypal and All Major Credit Cards.
