This pedal is based on the now famous amp-in-a-box Preamp pedal with one important tweak: the replacement of the first FET transistor with a germanium gain stage - stolen from the servo-biased Germanium Boost pedal which is ideal as a versatile gain stage since it reliably imparts a germanium tonality, mostly doesn’t care about temperature, and doesn’t affect frequency response. The result is an alternate universe take on their flagship pedal that marries the incomparable feel of the 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 you 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
