These are a genuine, real deal 1970s fender Jazz Bass single coil pickup set with it's original screws!
We took the bridge pickup out of a 73 Telecaster bass where the previous owner had routed a slot for a bridge pickup, and we purchased the 1975 neck pickup from a friend of the shop.
These sound as good as you would imagine and there is no issue with the performance of either of them at all.
It is also in very good condition apart from the front lacquer coming off the pole pieces - something that happens with pickups of this age.
Both show a healthy DC Resistance in photos.
