From Benson:

This pedal is based on our now famous amp-in-a-box Preamp Pedal with one important tweak: the replace- ment of the first FET transistor with a germanium gain stage (stolen from our servo-biased Germanium Boost pedal). The result is an alternate universe take on our flagship pedal that marries the incomparable feel of germanium with the careful equalization and tone controls of the preamp pedal.

The result is a slightly lower gain, but richer sounding and feeling overdrive/boost/fuzz/whatever we really, really dig. We hope you like it!

Beware: Germanium stops passing music at 120 Degrees Farenheit (like a very hot stage)

Power requirements: 9VDC Boss style adapter or battery 50ma

Controls: Gain (distortion), Treble (low pass filter), Bass (high pass filter), Volume
