The Gretsch FilterTron Neck Pickup Chrome is an electric guitar pickup featuring a humbucker design for the neck position with a chrome cover. The Filter’Tron head has two sets of six adjustable screw pole-pieces. Dual-coils are designed to “filter” out the hum that sometimes comes with single-coil pickups without getting too "muddy". These pickups now come with alnico magnets to produce a better and more vintage-authentic sound.
