Hi,
Do you mean this one?
http://filters.muziq.be/model/univox/superfuzz
Actually, the Shin Ei Companion, Fuzz/Wha/Siren, which is the same fuzz circuit, just different transistors, was the first fuzz I ever encountered and the words of Tom Wheeler " There may be a little more between you and Jimi Page than a fuzzpedal" were painfully obvious as in how do you even begin to make the sound of distorted amplifiers through such a beast? Well, maybe if you're Jimi Page
That is a memory that haunts me, and yes CAF is partly made to capture this inplayability
Hm, I haven't done any direct comparision, but let's say you can get similar sounds, close enough anyway apart from midnotch, which isn't featured on CAF.
Fuzzes that inspired the CAF, soundwise were
Maestro Super Fuzz
Gibson FZ-1A
Fox Tonemachine
Shin Ei Companion
Melos Square Wave
Marshall Supafuzz
Hm, what am I forgetting?
CAF won't sound exactly like any of them, but'd be my version of less playable fuzz
Have fun
BJ
