Germanium based units also comes with the lovely mystery surprise tone feature, the germanium components being temperature sensitive, ensuring that you will never know exactly what kind of tone you are going to get whenever you switch your germanium based pedal on next time, kind of like box of chocolates... or life.
Keeping things exiting and unpredictable.
Adjust your tone at room temperature at home, and get something entirely different from what you dialed in depending on weather you are doing an outside gig late in the autumn or high summer, or how much the stage light at a given venue is going to heat up your pedal board, ever changing as it adjusts to the different environment, making germanium based pedals tonal chameleons in the most true sense of the word.
