Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine sets an industry standard for enclosed tuning mechanisms, featuring an advanced 1:18 gear ratio that delivers exceptional precision and smooth tuning control. Each component is CNC-machined and surface-treated for maximum durability, while the self-locking drive ensures consistent tuning stability without slippage.
Equipped with high-grade brass string posts engineered precisely into the housing, these tuners provide reliable wear resistance and long-lasting performance. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw with a 0.39-inch diameter, eliminating tilt torque and protecting headstock mounting screws.
Permanently lubricated with Schaller special grease, these tuners operate completely maintenance-free. Designed with a 0.31-inch distance between the dual mounting pins and post center, they provide a rock-solid fit and effortless replacement for standard pegheads.
