For those wanting an accurate, even feel from their pickups, this passive, blade-type hum-canceling pickup offers vintage output and a flat response. The neck pickup has a subtle, warm character, which as a stand-alone replacement is great. This pickup uses a cover that is the size of traditional 5-string Fender Jazz Bass, which mean that, because it uses blades, it can be used on either 4-string or 5-string instruments. It will NOT directly retrofit a modern Fender Jazz V however. Will accommodate string spacings up to 2.9 (73.6mm) for both neck and bridge pickups.Combine with the 5-string bridge position Jazz Bass Stack for a perfectly matched set.Hand built in Santa Barbara, CA, the 5-string Jazz Bass Stack uses a ceramic bar magnet, 4-conductor leadwire, and is vacuum wax potted for squeal free performance.Seymour Duncan Item No. 11405-01Get yours today; with the security of our many decades of experience and Sam Ash Direct efficient order processing, your satisfaction is guaranteed!
