Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability. Engineered with a refined 1:18 gear ratio, it delivers ultra-smooth, exact tuning performance. All components are CNC-machined with high precision and surface-treated to ensure consistent self-locking engagement and exceptional wear resistance.
Equipped with high-grade brass string posts fitted seamlessly into the housing, the M6 Pin ensures optimal tuning stability. The innovative stepped M6 flanged washer centers the post securely through the hollow screw, removing lateral tilt and taking pressure off both the string post and rear mounting screws without requiring stepped headstock drilling.
Permanently lubricated with specialized Schaller grease, these closed tuning machines are completely maintenance-free. Designed for precise replacement and custom guitar setups, they offer robust build quality and enduring reliability.
