Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 represents the evolution of closed-gear tuning machines, setting a standard for precision and tuning stability. Engineered with an upgraded 1:18 gear ratio, it delivers ultra-smooth operation and precise adjustment for exacting performance.
Every component is CNC-machined to tight tolerances, featuring premium brass posts that fit securely within the housing to eliminate wear. The innovative stepped M6 flanged washer centers the string post accurately without requiring stepped headstock drilling, effectively eliminating tilt and relieving stress from mounting screws.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free and provide dependable, long-term performance across a wide range of instrument setups.
