Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability. Engineered with an improved 1:18 gear ratio, it delivers a remarkably smooth, accurate, and comfortable tuning experience for demanding guitarists.
Every component is CNC-machined to exact tolerances and surface-finished for premium durability. The self-locking gear drive pairs with high-grade brass string posts fitted seamlessly into the housing, ensuring long-term wear resistance and exceptional pitch retention.
Featuring Schaller's stepped collar washer, this tuner centers the string post securely through the threaded bushing without requiring stepped headstock drilling. Permanently lubricated with Schaller special grease, the enclosed housing provides reliable, maintenance-free performance.
