The Gotoh RES-O-LITE Series GB640 bass machineheads are premium, vintage-style replacement tuners manufactured in Japan. They are explicitly designed to combat "neck-dive" on electric basses by replacing heavy traditional hardware with super-lightweight materials. This classic open-back, standard-wind configuration features the signature metal cloverleaf ("elephant ear") buttons in a nickel finish. It uses strong duralumin to trim weight down to only 67 grams per tuner.
