Germanium is a chemical element with symbol Ge and atomic number 32, that’s used as a semiconductor in transistors and diodes, popping up in a few classic effects like the early period Arbiter Fuzz Face, the storied Dallas Rangemaster and the Maestro Fuzz-Tone. With that in mind, you may have noticed that some of our pedals ( Java Boost, Fuzz Head etc) use Germanium transistors to produce vintage inspired tones. Sometimes it’s planned out from the start, other times it’s a process of experimentation, but either way it’s always towards the greater good of our products. Without the explicit permission of the copyright holder.One facet of the design process here at Keeley Electronics comes down to selecting not just the highest quality components for use in our pedals, but the right component for the sounds we’re trying to achieve.
