Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine sets a high standard for closed tuning machines, combining legendary design with advanced engineering. Featuring an improved 1:18 gear ratio, it delivers velvety-smooth, highly precise, and stable tuning comfort. All components are CNC-machined to exact tolerances and surface-finished for dependable, self-locking performance.
Equipped with high-grade brass string posts precisely fitted into the housing, these tuners ensure maximum tuning stability and zero wear. The innovative stepped M6 flanged washer centers the string post securely via the banjonut, eliminating tilting torque and removing pressure from both the post and the rear mounting screws without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 Pin is engineered for lasting durability. Each set includes matching threaded bushings, stepped washers, and mounting hardware for straightforward installation.
