I just bought a used 80's Japenese Jazz Fretless. I would like recomendations on replacement pick ups.
Those things had good pups in them, but if ya really want to change, I recommend Seymour Duncan Antiquities. They are wonderful pups.
the problem is that the wiring seems to be ****ed up. and pups have sligh oxide stains on them. Is there a way I could save them? Whatever is cheaper.
You can probably deal with the oxide by using a non-metallic buffing pad like scotchbrite to clean them up. If the wiring is messed up, changing PUP's won't help. You can test the individual pickups by unsoldering them from the harness and soldering each on to a jack. Then plug the pickup straight into your amp with the volume low. Touch a screwdriver to each polepiece and you should get sound through the speaker if they are functioning. You can find generic Jazz wiring diagrams on the net to check that your wiring is correct. Also check all your solder joints. If you find you need to change pickups, the Antiquities are nice. I also have done a couple fretless conversions using the Duncan classic stacks with good results.
