Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine represents the legendary benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for precision and smooth tuning stability. Engineered with high-precision CNC machining and high-grade brass string posts, it provides dependable operation and wear-free longevity.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine centers the string post securely without requiring stepped peghead drilling. This design eliminates tilting torque and reduces mechanical stress on both the shaft and mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 180 directly replaces previous iterations without guitar modifications, making it an ideal upgrade for demanding players.
