Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin series sets the standard for closed tuning machines, featuring a precise 1:18 gear ratio for smooth, accurate, and stable guitar tuning. All structural parts are CNC-machined to exacting tolerances, surface-finished, and equipped with a self-locking drive mechanism that guarantees consistent performance.
Engineered for enduring durability, the high-grade brass string posts fit tightly within the housing to ensure optimal tuning stability and wear-free operation. Every closed tuner comes permanently lubricated with Schaller special grease, making the entire assembly maintenance-free throughout its lifespan.
Installation is streamlined through the innovative stepped M6 flanged collar with a 0.39 in (10 mm) base diameter, which centers the string post securely through the hollow screw. This smart design eliminates tilting moments, protects against mounting stress, and avoids the need for stepped headstock drilling.
