SEYMOUR DUNCAN / Seymour Duncan ANTIQUITY II / Antiquity II Jazz Bass Pickup / Jazz Bass Pickup Set I believe this is a very excellent pickup as a replacement pickup for Jazz Bass. If you replace the pickups on a Fender Japan or Squier, I think it will become an instrument that is one or two ranks higher. It is a pickup that is actually used by many professional users. This item was installed on a bass I owned once and then immediately removed. It is almost new, except for the wires being cut to the length for installation. The accessories are also as they were when new. Thank you for viewing. Thank you very much.
