Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an advanced evolution of a legendary standard, delivering exceptional tuning precision and velvety-smooth action. Featuring an upgraded 1:18 gear ratio, this closed-type tuning machine ensures unmatched fine-tuning accuracy and superior tuning stability. Every component is CNC-machined to exacting tolerances and surface-finished for a flawless, long-lasting performance.
Crafted with premium brass string posts, the M6 180 is precisely seated within its housing to eliminate wear and optimize resonance transfer. The unit utilizes a self-locking gear drive along with lifetime lubrication via specialized Schaller grease, making the entire assembly completely maintenance-free. Its stepped flanged washer centers the post reliably within a standard 10 mm peghead hole, preventing tilt and absorbing operational tension without requiring stepped headstock drilling.

Whether serving as a direct upgrade or replacing vintage units, it provides robust string retention and flawless intonation control. Designed to meet the demands of discerning musicians, it stands as an enduring benchmark in precision instrument hardware.
