Seymour Duncan SCPB 3 Quarter Pound Single Coil P Bass Pickup 

The vintage single-coil bass tone of this high output P bass pickup gets a push with more string sensitivity than the Hot model, and a more articulate treble response. The high output coil and quarter-inch diameter pole pieces give you aggressive attack with strong bottom end and lots of mids. It supercharges the traditional single coil with more tonal flexibility. This pickup is a drop-in replacement for any American Standard Single Coil Precision bass. Hand built in Santa Barbara, CA, the Quarter Pound for Single Coil P-Bass uses diameter alnico 5 rod magnets, Forbon flatwork, and is vacuum wax potted for squeal free performance.
