These are pickups removed from a Seymour Duncan Jazz Bass from the Yuumei Onkyo era. The CTS pots on the body were from 1980. They were functioning without issue until removal. The resistance is 7.9kΩ for both the rear and front pickups, which is lower than the SJB-1, the lowest output pickup in the current lineup. It is said that Seymour Duncan did not usually sell bass pickups as a standard lineup at the time. I don't think they would put pickups from another manufacturer on their own brand of bass, but since there is no product model number, the details are unknown. These are unidentified products as described above, but thank you for your consideration.
