Germanium OD Overdrive
Classic '60s Germanium transistor overdrive and more.
In addition to a Gain control, the Electro-Harmonix Germanium OD allows the user to control Bias for attack and the circuit Volts for that sweet spot found when a battery's voltage dips.
Dial up that slightly torn speaker sound OR dial in total Germanium "Satisfaction."
Germanium is an element like carbon or gold. Germanium transistors were used extensively back in the 1950s and ‘60s.
Eventually they were replaced by components that were considered “better.”
The EHX Germanium OD and Germanium 4 Big Muff Pi use these old school transistors.
They have a distinctive sound, some say smoother or “spongier.”
