I just picked up a second hand strat and the pickup poles are not aligned, they seem to be in pairs at three different heights (E-A strings medium height, D-G strings high, B-E strings low). At first I thought there was something wrong with the pickups, but the heights seem consistent across all three pickups so I guess this is intentional? They sound good either way, but it made me curious.
Has anyone come across this before? And if it's not meant to be like this, is there any way to adjust the height of pickup pole pieces?
(Bonus question - Is there any safe way to remove the rust?)
