Hey, I've got a question, but first some background: I recently got a 167 Gibson EB0 as a project bass, and the previous owner drilled an extra hole (*_*) for a 2nd output jack, why, I don't know. Anyway, I need something to put in the hole . I'm thinking, if its possible, of putting in a series/parallel switch like the new Fenders have. Can this be done with the Gibson humbucker, and if so, how? Thanks!
