This is a split coil hum cancelling design jazz bass neck pickup. They use the same hand wound pattern found on their NJ4's but with a finer wire called 43 gauge enamel. The natural character of this design is to have a more pronounced lower midrange, and a slightly muted high end. This makes them exceptionally suited to fingerstyle players. They are also totally humcancelling, and great for commonly noisy live situations.
