Was having a discussion with a buddy over the weekend and he had these questions.....thought I'd post to the gurus on this site. The "quack" sound from a Strat is using positions 2 and 4 (bridge and middle, middle and neck, with reverse winding on middle pickup), right? Is this because of the pickup combination being out of phase? Because the two coils of a humbucker are reverse-wound are they out-of-phase....if so, why don't they have this sound? (or did I have too many beers?)
