Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents the evolution of a legendary design, featuring an upgraded 1:18 gear ratio for smooth, precise, and stable guitar tuning. Manufactured with high-precision CNC components and surface finishing, these enclosed tuning machines deliver dependable performance and velvety operation.
Equipped with solid brass string posts that are precisely fitted into the housing, the M6 180 ensures maximum tuning stability and long-lasting, wear-free service. All enclosed machine heads are permanently lubricated with Schaller special grease, rendering them completely maintenance-free.
An innovative stepped M6 flanged washer (0.39-inch diameter base) reliably centers the string post without requiring step-drilled headstock holes. This structure eliminates tilting torque and absorbs mechanical strain from both the string post and rear mounting screws for seamless installation.
