Seymour Duncan Antiquity 4 string Guitar pickup. I believe this is for Electric Mandolin pickup model 1034-51 / 4.55k. Appears dusty but unused. Part of some old studio stock. Most of which has been tested. This has not been tested, but appears never to have seen solder or screws. I have potentially hundreds of items of guitar and studio equipment to list over the coming weeks. This will depend on success and feedback. Please be kind.
