Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry standard with its refined 1:18 gear ratio, delivering precise and ultra-smooth tuning action. Built with high-precision CNC-machined components and self-locking drive mechanisms, it ensures stable and sensitive tuning performance across all string tensions.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the post reliably without requiring stepped headstock drilling, eliminating tilting torque and reducing pressure on mounting screws.
Each closed machine head is permanently lubricated with specialized Schaller grease for lifelong, maintenance-free operation. Featuring dual rear positioning pins with 0.39-inch spacing, this unit is engineered for solid headstock mounting and dependable mechanical performance.
