I am still a relative newbie and have some set up questions maybe somebody could help with. Can somebody please explain how to properly adjust the height of my pickups. The only adjustments I have made to a p/u is that I once had to lower one side of the back p/u (closest to bridge) because the G string was buzzing on the p/u. Is there any kind of rule as to where they should be? As close to the strings as possible without buzzing? Would this (having p/u's adjusted to the optimum height) even have much effect on my tone?
