Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides precise, velvety-smooth tuning action and exceptional pitch stability. High-precision CNC-machined components and high-grade brass posts ensure smooth, reliable performance and long-lasting durability.
Equipped with an innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 Pin utilizes two mounting pins with a standard 0.39-inch spacing. It delivers rock-solid tuning support for solid headstock electric and acoustic instruments.
