The Seymour Duncan Antiquity II Jazzmaster uses hand ground alnico 5 rod magnets, with our special coil wind to deliver bright, 60s Jazzmaster tone that is glassy and crisp, with just the right balance of bridge position snap. Chords have a sharp, clear quality, and solos really jump out with that bright, 60s Surf tone. Use with the RWRP Antiquity II Jazzmaster neck pickup so that, when used together, they will be hum-canceling. This pickup is a drop-in replacement for any Fender American Standard sized Jazzmaster pickup, and will fit nicely into the existing cover.Hand built in our Custom Shop, this pickup uses hand ground alnico 5 rod magnets, a custom coil wind with heavy formvar mag wire, vintage-correct gray flatwork, cloth push-back lead wire, and they are all lacquered and wax potted like the originals.
