Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers state-of-the-art precision and reliable tuning comfort for modern musicians. Featuring an advanced 1:18 gear ratio, this closed-type tuning machine provides smooth, sensitive adjustment and exceptional stability. All individual components are CNC-machined and surface-finished to ensure uniform operation with a self-locking drive mechanism.
Equipped with high-grade brass posts precisely fitted into the housing, the M6 Pin ensures maximum tuning stability and wear resistance over extended use. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, eliminating tipping torque, relieving pressure from the mounting screws, and removing the need for stepped peghead holes.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. Designed with two alignment pins spaced 10 mm apart and a center-to-post distance of 8 mm, they offer a direct retrofit for matching headstock configurations.
