Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the evolution of an industry icon, setting the standard for closed tuning machines since 1966. Engineered with a 1:18 gear ratio, this model delivers precise, velvety-smooth tuning action and exceptional pitch stability. Every component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free operation.
Featuring high-grade brass string posts precisely fitted into the housing, the M6 180 ensures maximum wear resistance and zero backlash. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw without requiring a counterbore in the headstock, effectively eliminating tilting moments and relieving mechanical strain from both the post and mounting screw.
Designed with a compact housing footprint, the M6 180 retrofits seamlessly into original M6 configurations without modification. Available across a wide variety of configurations, finishes, button materials, and post styles, it offers uncompromising tuning accuracy and mechanical reliability for demanding guitarists.
