What do you all recommend as a starting point for pickup height? Some of the pics I've seen here have them so low they look like part of the pickguard, whereas mine are pretty high up there (especially the bridge pup). Also, I see that the general consensus is to have them pretty low, but why is that? Wider dynamic range? Something tonal? Less pull on the strings by the magnets? And why are the heights Fender recommends so high? If it means anything, mine is an Am. Dlx. with the SCN's, no mods outside of the occasional string change.
