A brand new Seymour Duncan SJB-3 Quarter Pound Jazz Bass Bridge Pickup.  

FROM SEYMOUR DUNCAN:

The Quarter Pound Jazz Bass pickups have it all: hot output, great attack and massive attitude. The 1/4” diameter poles and hot coil winding deliver a full, even response with great sustain and sonic complexity for a powerful tone suited to any genre. You get the higher output of an overwound coil, with the articulation and detailed high end of a vintage pickup.

These pickups are drop-in replacements for any American Standard Jazz Bass (Mexican Standard Jazz Basses use two neck-sized pickups).  Hand-built in Santa Barbara, CA, the Quarter Pound for Jazz Bass pickups use Alnico 5 rod magnets and Forbon flatwork and are wax potted for squeal-free operation.
