Mojo is part feel and part sound. Between a blacktop strat, an EsP ltd, and a schecter classic, I go for the thin neck profile because I am learning to play with a more classical geip. So the strat and and the esp have the feel. In terms of sound, after feel is sorted, it is some kind of wood to pickup resonance thing. I can say that my esp does not have the same mojo-ness as my strat - it needs a pickup change to get mojo-ed.
