Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine sets a high standard for closed tuning mechanisms, combining classic heritage with modern precision engineering. Equipped with a refined 1:18 gear ratio, it delivers ultra-smooth, delicate, and highly accurate tuning stability for exceptional performance.
Crafted with CNC-machined components and high-grade brass string posts, these tuners feature a self-locking drive designed for wear-free durability. The innovative stepped M6 flanged washer centers the string post reliably through the banjonut, eliminating tilting torque and protecting the instrument headstock without requiring stepped drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 Pin utilizes a two-pin indexing system with a 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) center-to-pin distance. It provides a direct and reliable upgrade for precision tuning stability.
