I've had some WCR Strat pickups that I could safely lower the pole piece height by simply pushing the pole piece from front to back. I did this at Jim's recommendation to lower the G string magnet. Is this safe to do with other new production, vintage Strat type pickups? Those high G string magnets drive me crazy with flatter radius necks. I've been thinking of trying some Fender Fat 50s, but want to lower that G magnet.
