This pedal is based on the famous amp-in-a-box Benson Preamp pedal with one important tweak: the replacement of the first FET transistor with a germanium gain stage - stolen from their 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 the flagship pedal that marries the incomparable feel of the germanium with the careful equalization and tone controls of the preamp pedal.
