Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original closed-housing tuner introduced in 1966, this modern iteration incorporates state-of-the-art CNC machining and durable brass string posts engineered for maximum tuning stability and zero wear.
Featuring the innovative stepped M6 flanged washer, this tuner allows smooth installation and rock-solid shaft centering without requiring a stepped headstock counterbore. The smart washer design eliminates tilting torque while relieving direct pressure from the string post and rear mounting screw.
Each closed housing is permanently lubricated with Schaller special grease for completely maintenance-free operation. Designed to match standard retrofits, the M6 180 seamlessly replaces previous models to upgrade your instrument's performance and reliability.
