yeah i knew what you meant i was new to it at one time myself :-D, Si fuzz pedals are just as fiddly as Ge boxes, the designs of fuzz pedals in general is the reason, in a fuzz you really aren't boosting the signal to clipping like in a amp or a diode clipper, a fuzz pedal you are saturating one of the transistors in the circuit that is kind of what gives fuzzes their unique sound.

long story short a fuzz pedal is picky regardless of whether it's Si or Ge, which is fine as long as you aren't picky about how it sounds :-D
