Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry standard for closed tuners, featuring an upgraded 1:18 gear ratio for velvety smooth, highly precise tuning stability. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Equipped with high-grade brass string posts engineered precisely into the housing, this tuning machine provides maximum wear resistance and rock-solid pitch retention. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing, eliminating tilting torque and removing strain from the post and mounting hardware without requiring stepped headstock holes.
Engineered with a 0.39-inch (10 mm) center-to-center pin spacing and a 0.31-inch (8 mm) spacing from pins to post center, the M6 Pin delivers a dependable fit for solid headstocks. Self-locking drive engineering ensures sensitive, consistent, and backlash-free adjustments across all performance conditions.
