This a 1972-1978 Jazz Bass Neck I rewound. I am not certain of the date but it ranges from 72-78 as the serial number is very faint. The pickup reads 7.3k and was wound with 42 gauge plain enamel wire to original specs. It is lacquered and the original leads reinstalled. The original cover is also included. I received this pickup non-functioning in trade. My standard functional warranty applies.
