Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuning mechanisms, combining timeless aesthetics with contemporary engineering. Featuring a refined 1:18 gear ratio, it delivers ultra-precise, velvet-smooth tuning and exceptional stability. High-precision CNC-machined components and a self-locking drive ensure sensitive, reliable adjustments across all playing environments.
Equipped with durable brass posts precision-fitted into the housing, this tuning machine provides maximum wear resistance and lasting pitch retention. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring a stepped peghead bore, eliminating tilting torque and reducing structural stress on both the post and rear mounting screws.
Permanently lubricated with Schaller special grease, the enclosed mechanism remains completely maintenance-free throughout its service life. Designed for seamless installation, the two-pin configuration offers solid positioning with a 0.39 in center-to-center pin spacing.
