You know Rich L -- I didn't even bother to respond to the
silicon versus germanium post here.
They can sound really different and since tone is subjective
I'll leave it to the player (or the listener) to decide which
is best for their needs.
And the more cascade you have (fuzz face = 2 cascading and
tone bender = 3 cascading germs or silicons) then the differences
become more and more obvious. yes - there are 'hybrid' fuzz faces
that use 1 germ and 1 silicon.
But I have lots of germanium fuzzes - from Analogman, Pro Analog and many other
boutique makers and home made pedals. I also have a box full of well made
silicons from indie makers. The only people that would claim the
differences are all nonsense must have tin ears.
The germ's (especially the NOS mullards) have a much smoother response
and unlike most silicons, if the pedals are made properly they still
allow variances of tones based on pick attack. Usually silicon fuzzes
pretty much can make every guitar played through them sound pretty much
the same and lose the individual character of the guitar being played
through it and they also do not change tones whether you pick soft or dig in.
Silicons sound much more aggressive that germ. fuzzes and germ. based treble boosters (single transistor pedal)
I'm not arguing which one is better - but they are most definitely different
in their sounds. The silicons can get down right nasty (which can be a cool thing actually)
Ah well - the posers out there that say there is no difference
or that using NOS germaniums is some phooey nonsense are simple posers
that wouldn't know the difference between a cat screech and a dog barking.
Believe me RichL - you'll never lose that $200 bet - at least not around my way.
