Seymour Duncan's Hot Rails for Strat is a single-size humbucker. This is an official product of ESP. How about it for those who want to give their Strat or single-coil guitar a powerful sound? I think it's the perfect pickup for rock and metal, as it's also used by the guitarist of Iron Maiden. Two are listed, but the lead wires are short because both were installed on a Mustang. They were used until recently, so there are no problems with their use. They were removed at a shop and the continuity has been confirmed. Due to the nature of pickups, please install them at your own risk. If you are not good at wiring, we recommend having them replaced at a shop. - Brand: Seymour Duncan - Model Name: Hot Rails for Strat - Color: White - Accessories: Original box, mounting screws
