Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine set delivers exceptional precision and tuning comfort with an advanced 1:18 gear ratio. CNC-machined components and surface-finished parts ensure consistent, sensitive, and stable tuning performance with a self-locking drive.
Equipped with high-grade brass string posts engineered for wear-free durability, these enclosed tuners are permanently lubricated with Schaller special grease for maintenance-free operation. The stepped M6 flanged washer centers the string post reliably without requiring a stepped peghead bore, eliminating tilting torque and reducing pressure on the mounting screws.
Designed for seamless installation, this configuration features a dual-pin mounting base with a 0.39-inch (10 mm) center-to-center pin spacing and a 0.31-inch (8 mm) distance from pins to the center of the post. It includes all necessary banjo bolts, flanged washers, and mounting screws for complete installation.
