Do you love the sound of your vintage Fender® bass but wish it had more low range? Well, wish no more! A long time open secret among the world's best bass players, the Hipshot® Xtender gives you the best parts of a 5 string bass in a 4 string package. With the flip of a lever, drop your E string to D (or even B) and back again! The BT3 is a direct replacement for pre-CBS Fender basses equipped with Kluson® reverse wind tuning machines. This tuner is also featured on countless reissue models and custom builds.
