Pigtronix Philosopher's Tone Germanium Gold Micro
What makes the Germanium Gold version unique is the GRIT control. More than a simple gain knob, the Grit knob found on the Philosopher's Tone Germanium Gold Micro acts as a blend for the germanium-enhanced distortion found in this unit. You can dial in more or less grit, depending on your tastes.
Germanium
As a semiconductor, germanium allowed the production of a solid state equivalent to the diode. Like most semiconductors, germanium can have impurities added to make it an electron donor - a so-called n-type material - or an electron acceptor, called p-type. By marrying p and n type strips of germanium, the element provided the same diode effect.

Germanium Can Take Transistors Where Silicon Can't – DSIAC
Nearly 70 years ago, two physicists at Bell Telephone Laboratories—John Bardeen and Walter Brattain—pressed two thin gold contacts into a slab of germanium and made a third contact on the bottom of the slab. The flow of current through this configuration could be used to turn a small signal into a larger one.
