Benson Germanium Boost

From Benson: NERD ALERT When designing the temperature controlled fuzz, we tried some unusual approaches. One false start utilized a voltage controlled error correction circuit to bias a single germanium transistor. It ultimately didn’t work for the fuzz, which is comically sensitive to transistor gain attributes. We did find a place for it though. It turns out it was PERFECT for achieving a germanium clean boost that, (like our fuzz) is impervious to component drift, leakage, and temperature....moreso in fact. We also fixed a couple other issues preventing the germanium transistor from being used as a convinc- ing linear boost...we increased the input headroom (even a normal guitar signal will drive a germanium transistor into unwanted input distortion without some tweaks) and increased the input impedance (a BJT transistor would normally thin out bass frequencies and interact negatively with whatever flows into it). The result is a germanium clean boost that can utilize a germanium t
