I've been trying to build a fuzz face clone off the net and have been comparing a number of schematics and layout diagrams. Of course, every one I've looked at has slight differences. This one at http://smallbox.zeonhost.com/projects/fface/ looked like the easiest to me, so I've attempted to build it a couple of times and haven't had any real success - it bypassed fine but only gave me a very, very quiet signal when engaged. I just wanted to know if anyone with any experience in building fuzz face clones thinks this layout diagram looks right. The linked page with a downloadable parts list seems to suggest that this a PNP circuit, however it is running off positive power and a negative ground which seems to be the reverse of what the designer of the Axis Fuzz Face at http://fuzzcentral.ssguitar.com/fuzzface.php recommends for PNP circuits. So, if this is the case the can capicitors in the first diagram may also be incorrectly aligned for a PNP fuzz. If it is the wrong way around for PNP would it be fine to use for a NPN circuit instead? Or more generally has anyone got any pointers for me on the first link's diagram that will help me to get the circuit working?
