This pedal is based on Alexander Pedals 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 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 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. We hope you like it!
