Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an optimized 1:18 gear ratio. All components are high-precision CNC-machined, surface-finished, and equipped with a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning.
Equipped with high-grade brass posts precisely fitted into the housing, these tuners ensure maximum tuning stability and wear-free performance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilt and removing mechanical pressure from both the post and mounting screw without requiring a stepped peghead bore.
Featuring permanently lubricated internal gears with Schaller special grease, these sealed tuning machines offer completely maintenance-free operation for long-lasting reliability.
