Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine represents high-precision engineering with a refined 1:18 gear ratio, delivering smooth, sensitive, and accurate tuning stability. Building on the legacy of the original closed-housing design established in 1966, this version integrates CNC-machined components and surface finishes designed for long-lasting performance.
Equipped with high-grade brass string posts engineered precisely into the housing, the mechanism provides wear-free operation and solid pitch retention. The stepped M6 flanged washer centers the string post securely through the banjo bolt, removing tilt moment and eliminating the need for stepped headstock drilling.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. The compact housing dimensions allow direct replacement of previous versions without requiring headstock modifications.
