That familiar tonal character is all there the bridge position upper mids that cut through so nicely, and the neck position warmth and articulation. Each Antiquity JBJazz set is hand built with the same original materials that we used to make them in the 70s, including long legged nickel silver bottom plate, maple spacer, original Jazz and JB model stamp, rough sand cast alnico 5 bar magnet, heavily aged butyrate bobbins, and vintage style push-back braided single conductor lead wire. The electronic and cosmetic treatments of our proprietary Antiquity aging process give these pickups the look, sound, and feel of a real-deal set of 70s Seymour Duncans.
