Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine combines legendary design with advanced precision engineering. Engineered with an improved 1:18 gear ratio, it delivers an exceptionally smooth, accurate, and stable tuning experience. CNC-machined components with self-locking drive mechanics ensure lasting durability and reliable tension retention.
Crafted with premium brass string posts fitted directly into the sealed housing, the tuning machine achieves maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilt torque and the need for stepped headstock drilling. Permanently lubricated with Schaller special grease, the enclosed design remains completely maintenance-free.
Featuring dual mounting pins positioned with a 0.39 in center-to-center spacing and a 0.31 in post-to-pin distance, this unit provides a direct retrofit for standard M6 pin configurations. Available in diverse button styles and post configurations, it fits solid headstocks seamlessly while maintaining effortless, sensitive tuning performance.
