Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability, equipped with a 1:18 gear ratio for smooth and ultra-fine adjustments. Building upon the legendary 1966 closed-housing architecture, modern engineering improvements deliver superior handling and flawless performance.
Precision CNC-machined components and high-grade brass string posts ensure virtually wear-free operation and exceptional durability. The internal self-locking drive and high-grade permanent lubrication guarantee maintenance-free reliability over years of rigorous play.
Installation is streamlined through an innovative stepped flanged washer with a 0.39-inch diameter, centering the string post securely without requiring stepped peghead counterbores. This design eliminates tilting torque and protects both the post and mounting hardware from unnecessary tension.
