I used [this layout] which is the nashville circuit but I swapped the input and output caps for .1uf... it does a really cool octave thing as the notes sustain... Killer fuzz!
Thanks for all the info you guys posted here!

I don't know if the circuits are that similar, other than being two-transistor fuzzes. To my eye, the bosstone looks like Q1 is a discrete, high gain boost circuit, a bit like the first transistor of a big muff or EHX LPB-1 booster (biased with two base resistors and a collector resistor on Q1, but running at max gain with a grounded emitter instead of a resistor/resistor+cap to ground), which then goes through a buffer formed by Q2. The heavily boosted, buffered guitar signal then has hard clipping applied with the diodes.
The fuzzface is a bit different because it has the two transistors used a single boost/fuzz stage, and no diode clipping: There is a different style of base biasing of Q1 (via feedback from Q2's emitter) so the way clipping reacts to absolute guitar input level is going to be different. There is a long and detailed explanation of this at [url=rgkeen's technology of the fuzzface]http://www.geofex.com/article_folders/fuzzface/fffram.htm[/url]
