Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this updated version features precision CNC-machined components and high-grade brass posts engineered for wear-free operation and maximum tuning stability.
Equipped with an innovative stepped M6 flanged washer, installation is streamlined while reliably centering the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screws.
Permanently lubricated with specialized Schaller grease for maintenance-free performance, the self-locking drive ensures smooth, sensitive, and reliable string tuning across all playing styles.
