Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision, stability, and smooth tuning performance with its refined 1:18 gear ratio. All components are precision CNC-machined and surface-treated, featuring a self-locking drive mechanism that ensures sensitive and reliable adjustment across all playing styles.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear-free operation. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on the mounting components.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 Pin utilizes a two-pin mounting layout designed for seamless installation and robust alignment. It comes complete with threaded bushings, washers, and mounting screws for secure fitment on solid headstocks.
