Sand-cast Alnico V magnets on the 3 low strings add more definition and punch to the bottom end. Sand-cast Alnico II magnets on the 3 high strings provide a warm and smooth top end without sacrificing that great Tele quack. Tele players often complain that their low strings sound "mushy" and their high strings are too bright - especially in the bridge position. The Five-Two concept counteracts this phenomenon. If you look closely at the pickup, you can actually see the difference between the 2 magnet types. Designed for the bridge position.
