These are custom Jazz Bass pickups I made for a new builder who ran up on hard times. They are brand new in the box and unused. The pickups are flat pole solid top covers. They are wound with 11,000 turns each of 42 Plain Enamel coming to 9.6k in the neck and 9.8k in the bridge. RWRP hum-cancelling pair. They are potted and have cloth leads. The tonal aspects are very full and round sounding with a big bottom. My normal functionality warranty applies but these are heavily discounted and ALL SALES ARE FINAL and the tonal warranty does not apply. There are only two sets of these available.
