I am building a basic NPN fuzz face pedal and I am looking for a pair of NPN Germanium transistors. I have heard that the exact type of transistors it up to taste, but will this work?
Asked by Joey Blanchard on October 17th, 2022.
They will, but you would need to either select two of these from a batch of them, or select the other components based off the ratings of two specific transistors.
