The 2 major contributors are guitar type (LP, SG, Tele etc) and amp, after that I'd say comes the pups, the wood/build quality of the guitar and the speakers in the cab, the guitar quality and pups will swap priority depending on the combination. Warpigs will dominate anything, Mules will be more influenced by the wood etc.
:lol: this thread sucks, and is a bit off topic, but anyway: I disagree with you on what makes your sound, the fingers play a huuuuge part I think, and I sound similar on most things with a different flavours.
I agree with the rest of that though, just thought that was a big thing you missed
ie, manhatten pickups won't make you sound like a jazz player
