Seymour Duncan Quarter Pound Jazz bass pickup set
From the manufacturer:
Quarter-inch diameter Alnico 5 rod magnets and hot coil windings deliver attitude and power.
One of our most popular bass models, the Quarter Pound for Jazz Bass was designed to take your bass tone to new heights. This neck and bridge pickup set has it all: hot output, great attack and massive attitude. The 1/4” diameter pole pieces and hot coil windings deliver a full, even response with great sustain and complexity that are at home in any genre of music. The neck pickup is RW/RP (reverse wind reverse polarity) for hum cancellation when both pickups are used together. These pickups are a drop-in replacement for any American Standard Jazz Bass.
Hand built in Santa Barbara, CA the Quarter Pound for Jazz Bass uses Alnico 5 rod magnets and Forbon flatwork, and is wax potted for squeal-free operation. Comes with black cover.
Magnets: Alnico V
