I've got a guy who wants me to build him a fuzz face and he requested a rotary switch for tone adjustments, and it reminded me of the "tweak" function on Seymour Duncan's Tweak fuzz. I found a schematic here: http://analogguru.an.ohost.de/193/schematics/SeymourDuncan_TweakFuzz.gif
It looks to me like a fuzz face with some funky business going on with the input capacitor. As I interpret it the rotary switch allows you to select varying values of the input cap creating an odd sort of tone control. Its a sweet concept and I'd like to get it into a fuzz box for this guy.
1. I'd like some confirmation that this is in fact a fuzz face derivative with the rotary switch sorting through different input caps, I am not very proficient with schematics so I may very well be wrong
2. Where does one get a switch like this and how do you wire it? I've done this same sort of concept with a dpdt switch to give options with different caps or diodes. I am not familiar with this kind of switch though.
3. Any other ideas about how to get this sort of tone adjustment into a fuzz face? I'm open to being creative and don't have to stick to the Tweak Fuzz by the exact specs.
I'll start with a breadboard build and fool around from there. Once I get it all sorted out I'll put it into an enclosure via veroboard. Thanks in advance.
Here's a pic of the schematic:
