I've got 2 silicon fuzz face style pedals, both with BC108's - one sounds thick and wooly and the other is quite a bit brighter.
Is it just the difference in transistors that affects the brightness of the tone or is there something else in a fuzz face circuit that affects this?
Also, I wouldn't mind messing around with different transistors, and particularly want to try BC109's and BC183's - anyone know where I can get hold of these in the UK? I've read up on the Geofex "Technology of the Fuzz Face" article and there are a number of suggested gain ranges to try but I'm struggling to find anywhere that stocks gain matched transistors.

I love my ultrastoner, jumbo tonebender and zoom ultra fuzz pedals, though it's fair to say none clean up like the axis fuzz, which will do a wonderful crystal clean.
Let's say we're sticking with silicon variants, which component in the circuit would you say has the biggest effect on tone?
Great thing, though I broke the pcb when I smashed a pot. Oops.
I'd have another though. Even with pickups hot enough to cause squish in the tone, just max volume, max gain, take a hair off each until it's not squealing and voila, clean as you like, crunchy as you like, filthy as you like.
