I have had these pickups for less than a week, they sound great but I prefer pickups without exposed magnets. Here is the information about the pickups. Items come in original packaging asking $150 shipped, they are $185 new! NJ5F These are Fender Jazz 5® replacement pickups. They will fit into your existing covers and make your 5 string Fender® come to life. They are based on the same formula that makes Nordstrand's NJ4 pickups sound so good: Alnivo V magnets and Heavy Formvar 42 gauge wire wound in a simulated hand pattern. They have a nice growly bridge pickup tone, a big full neck pickup tone and a huge deep earth shaking tone with both pickups on. They will definitely make your bass sound better! These also fit Lakland® Joe Osborn 5 (US and Skyline versions). Includes black covers. Pickup length: Bridge = 4.10", Neck = 3.965"
