Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning stability, featuring an advanced 1:18 gear ratio for smooth, accurate adjustments. Every component is CNC-machined to exact tolerances and surface-finished, utilizing a self-locking drive mechanism to guarantee consistent and reliable tuning performance.
Engineered with premium brass string posts precisely fitted into the housing, the M6 180 ensures maximum wear resistance and enduring stability. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing strain on mounting hardware.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, this enclosed tuning machine offers seamless replacement compatibility with earlier M6 models while providing refined mechanical performance.
