Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers precision tuning and stability with an improved 1:18 gear ratio for smooth, precise adjustment. Engineered as an evolution of the landmark sealed tuning machine design, it incorporates CNC-machined components and self-locking drive mechanics for consistent tuning accuracy.
Crafted with premium brass string posts fitted precisely into the housing, this machine head features an innovative stepped flanged washer that centers the post securely via the banjo bolt. This specialized washer eliminates tilting torque and protects both the string post and rear fixing screws without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 Pin utilizes a two-pin rear mounting configuration with a 0.39 in (10 mm) pin spacing and a 0.31 in (8 mm) distance from the pins to the center of the post.
