This set includes the Seymour Duncan Hot Stack STK-J2b Bridge and the STK-J2n Neck pickups.
The Seymour Duncan STK-J2 Hot Stack pickup is a hum-cancelling stacked J-Bass pickup with increased output and fatter tone for any 4-string Fender American Standard Jazz Bass.
Seymour Duncan took the noiseless Classic Stack and ratcheted up the tone another notch. For this pickup they increased the output and thickened up the mid-range response, which gives rock tones an added push without getting harsh. This hum-cancelling pickup is designed as a drop-in replacement for Fender American Standard Jazz Bass bridge position pickups.
NOTE: The STK-J2b Bridge pickup is the slightly wider American sized Jazz Bass bridge pickup (3.705" wide). If you have a Mexican Standard, you will likely need to use two STK-J2n Neck pickups, as the pickup slots are both neck-sized on that model.
The Seymour Duncan Hot Stack J-Bass pickups use Alnico 5 rod magnets, Forbon flatwork, 4-conductor leadwire, and are vacuum wax potted for squeal-free operation. Each pickup is hand built in Santa Barbara, California.
