These early designs, using now-coveted NKT-275 Germanium transistors, varied greatly with guitar output level and pickup impedance, and players like Hendrix and Gilmour preferred Stratocasters for this very reason, cranking the knobs on the pedal and using the guitar's volume and tone controls to vary from clean to over-the-top dirty and all ...

Germanium Properties, History and Applications

Germanium transistors had a tendency to fail at high temperatures, a problem that could be solved with silicon. Until Teal, no one had been able to produce silicon with a high enough purity to replace germanium, but after 1954 silicon began replacing germanium in electronic transistors, and by the mid-1960s, germanium transistors were virtually ...
