Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and smooth tuning performance with its refined 1:18 gear ratio. As the modern evolution of the legendary original closed-type machine head introduced in 1966, it features high-precision CNC-machined components with premium surface finishing and self-locking drive mechanics for exceptional stability.
Equipped with high-grade brass string posts meticulously fitted into the housing, this machine head guarantees maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer ensures effortless installation and solid centering without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on mounting components.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 180 is engineered as a direct replacement for previous iterations while maintaining flawless reliability. The set includes threaded bushings, step washers, and mounting screws for complete installation on solid or slotted headstocks.
