Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. Designed with high-precision CNC-machined components and premium surface treatments, it ensures consistent, sensitive, and reliable tuning stability.
Equipped with wear-free high-grade brass posts fitted seamlessly into the housing, each unit features Schaller special permanent lubrication for entirely maintenance-free performance. The self-locking drive keeps your instrument securely in tune under demanding playing conditions.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post precisely through the hollow screw without requiring stepped peghead counterbores. This design eliminates tilting torque and protects both the post and rear mounting screws from unnecessary pressure.
