Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin Guitar Tuning Machine brings legendary design into refined modern performance, featuring a precise 1:18 gear ratio for smooth, accurate tuning. Every component is CNC-machined to exacting tolerances and treated with a high-grade surface finish, while a self-locking drive mechanism delivers consistent, sensitive tuning stability.
Equipped with high-grade brass string posts precision-fitted into the housing, this tuning machine guarantees maximum durability and zero-play operation. The innovative stepped M6 flanged collar eliminates the need for stepped headstock drilling, centering the string post effortlessly and preventing mechanical tilt.
Permanently lubricated with Schaller special grease for completely maintenance-free longevity, the M6 Pin utilizes a two-pin rear mounting pattern with a 0.39 in center-to-center spacing. The package includes hollow screws, stepped flanged collars, and mounting screws for secure and straightforward installation.
