Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. As the modern evolution of the legendary original sealed tuning machine established in 1966, it incorporates state-of-the-art engineering while preserving its classic heritage.
Precision CNC-machined components and high-grade brass string posts ensure velvet-smooth operation, exceptional tuning stability, and wear-free performance. Each sealed unit is permanently lubricated with proprietary Schaller grease, making the mechanism completely maintenance-free.
Equipped with an innovative stepped M6 flanged washer with a 0.39 in diameter, the tuner centers the string post securely over the hollow screw without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screw.
