Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and smooth operation with an upgraded 1:18 gear ratio. All components are CNC-machined to exacting tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent, ultra-fine tuning stability.
Equipped with premium brass string posts precisely fitted into the housing, these tuners offer unmatched wear resistance and long-lasting tuning reliability. Closed-housing construction is permanently lubricated with Schaller special grease for completely maintenance-free performance.
An innovative stepped M6 flanged collar allows straightforward installation and self-centers the string post through the hollow screw, preventing tilting force and eliminating the need for stepped peghead drilling.
