QA pickups are hand wound in the USA. Our limited edition pickups are made in very low quantities. This QA Retrospect 59 Replica pickup set is hand wound using 42 AWG purple plain enamel wire, 49.2mm spacing, aged double black butyrate bobbins, double black leads. long legged nickel silver baseplates and A2 long rough cast magnets, brass baseplate screws, aged pole screws and slugs. They have tooling marks similar to 50s pickups and Patent Applied Stickers that "glow" just like the real deal QA 59 Retrospect pickups are non potted. The Replica 59 models are sold as a set only and resistance falls around 7.7 ohns at the neck and 8.6 at the bridge. This set will provide that vintage bell chime with just a tad more punch from the bridge for those searing leads. These look and sound just like 59s!!
