Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features an enhanced 1:18 gear ratio for precise, velvet-smooth tuning and maximum stability. Engineered as an evolution of the legendary original sealed tuner, all components are CNC-machined with high-precision tolerances and self-locking drive functionality.
Solid brass string posts are precision-fitted into the sealed housing to resist wear and prevent pitch drift. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped peghead bore, eliminating tilting torque and reducing mechanical stress on mounting screws.
Permanently lubricated with Schaller special grease, this tuner provides maintenance-free performance across extensive use. Designed to replace legacy M6 tuners without instrument modification, it delivers modern tuning precision and robust hardware construction.
