The Jazzmaster pickups are single-coil with a hotter output that can be dialed back for some surf or cranked up for a grittiness that delivers. This pickup is a drop-in replacement for universal Jazzmaster-sized pickups and will fit perfectly into the original cover. They are built with AlNiCo 5 magnets, Fiber Bobbins, and cloth push-back leads. The pickups are wax potted and the cover, screws and foam spring are included.
