[quote name='GarethFlatlands' post='1001533' date='Oct 26 2010, 06:55 PM']Cheers, will do. I reckon I might need some help on component changes for switching NPN and PNP circuits, adding a blend control and improving bass response.
Got 4 boxes coming, 2 * 1 knob, 2 * 2 knob and a 5 knob. I reckon a couple of fuzz faces, (1 AC127 germ and one BC108 Si), a couple of one knob fuzzes (ie colorsounds) and either a fuzz factory or a wooly mammoth clone, although I'm open to suggestions.
Edit:- here's a list of the transistors I've got so far to play with.
8 * BD139 (possibly useless for fuzz)
4 * gain selected (2 pairs) AC127
20 * BC108
6 * BC109B (might use a couple of these for modding my Crybaby)
2 * gain selected 2N404
6 * AC176[/quote]

There's some interesting vintage fuzz circuits here using BC108s that don't get made commonly.
