This is a brand new Blacktop FilterTron neck pickup in chrome with bezel and mounting hardware included. It will fit Gretsch and many other humbucking pickup equipped guitars. These use a ceramic magnet rather than an Alnico V as used in the HS FilterTrons. They have more of that unique sound of the Gretsches heard on the recordings of the 60's. This is one of their most popular humbuckers used on many of their current models, and responsible for that "great Gretsch sound". Retails at $39.99.
