I replaced the neck and bridge pickups in my Deluxe Nashville Tele with SD Alnico Pro II Tele pickups. I kept the middle pickup (Fender Tex Mex Strat pickup which is Alnico 5 magnet) from the stock set. After the fact, I'm wondering if that is a no-no....mixing magnet types? Is this (2 different types of magnets in a set) a potential issue/concern? It didn't even occur to me when I researching/deciding on the replacement pickups. I'm using a Fender SuperSwitch (5 way) to get neck, neck/middle, neck/bridge, middle/bridge and bridge. Anyone with experience/knowledge about this?
