Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for closed-type tuners, combining legendary heritage with modern precision engineering. Featuring an improved 1:18 gear ratio, it delivers ultra-precise, velvet-smooth tuning and exceptional tuning stability. Every component is CNC-machined to exacting tolerances and treated with high-grade surface finishing for lifelong, wear-free performance.
Equipped with Schaller's innovative stepped collar washer (0.39-inch diameter), the string post is centered securely via the banjo bolt without requiring stepped peghead counterbores. This design eliminates tilting torque and relieves mechanical stress from both the post and mounting points. High-grade brass string posts and permanent Schaller special grease lubrication ensure frictionless operation with zero maintenance required.
Engineered with a standard 0.39-inch center-to-center two-pin spacing, the M6 Pin offers direct housing compatibility with previous single-pin Schaller models. The distance between the mounting pins and post center measures 0.31 inches. Each set comes complete with banjo bolts, flanged washers, and M2.2 x 0.37-inch mounting screws for seamless headstock installation.
