Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision, tuning comfort, and long-lasting stability. Engineered with an upgraded 1:18 gear ratio, it delivers an exceptionally smooth, accurate, and reliable tuning experience across all styles of play.
Every component is precision CNC-machined and surface-treated, featuring premium brass posts accurately fitted into the housing to eliminate wear and ensure absolute stability. High-grade Schaller special grease provides permanent internal lubrication, making the fully enclosed housing completely maintenance-free.
Equipped with an innovative stepped M6 flanged washer, this tuner reliably centers the string post via the banjo bolt without requiring step-drilled headstock holes. This design eliminates tilting torque, relieving pressure from both the post and rear mounting screws for seamless installation and enduring structural integrity.
