USED BENSON / Germanium Fuzz [04]

Benson Amps / Germanium Fuzz is now in stock.

The Germanium Fuzz is a Germanium Fuzz with "Thermal Bias Control".
It uses two germanium transistors, 2N527 and 2N404, and was designed using 60's Fuzz circuit theory to maximize its capabilities. The "Thermal Bias Control" function, one of the features of this unit, has been added to this circuit.

Thermal Bias Control" for the best sound
Germanium transistors are very delicate, and the bias between the capacitors changes depending on the temperature of the capacitors. In this unit, a heater gently and automatically warms the capacitors to the proper temperature when the power is turned on. This means that the best performance can be obtained regardless of the outside temperature. It takes 2 to 3 minutes after turning on the power to start using the unit, as it needs to wait for the condenser to reach the proper temperature.

After the power is turned on, the LED will light up orange. This is an indication that the device is "warming up," and the hFE (transistor gain) is increased to the specified value to adjust the bias to the correct voltage. When the proper temperature is reached, the heater turns off and the LED turns green to indicate that the device is ready.
The LED may go back and forth between orange and green during operation, but this is not a malfunction. The heater operates as necessary to ensure that the circuit is always at the proper temperature.
The unit is designed to operate normally at ~ approximately 37.8°C. We were so concerned about temperature that we chose white as the enclosure color because tests have shown that in direct sunlight, the white enclosure has an internal temperature approximately 7°C lower than the black enclosure.

IMPEDANCE Control and Class A Buffer
The IMPEDANCE knob controls the input impedance. At low settings, even at high gain settings, the sound is tight, as if the volume of the guitar itself is turned down. However, a low impedance setting will have a negative effect on the sound when a buffer or other effects device is connected in front of it. So we added a Class A buffer to the input section. This buffer uses a passive pickup simulator circuit like Jack Orman's (the world's first guitarist to create a compact effects pedal), which uses audio transistors as induction coils, resistors, and capacitors.
This buffer eliminates problems that occur when connecting to other effectors, and allows connections that were previously considered impossible, such as connecting a booster in front of it.

This unit has some signs of use, but there are no operational problems.
