Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine sets an industry standard for precision and tuning stability with an improved 1:18 gear ratio. Designed for smooth, velvet-like operation, each component is CNC-machined to exact tolerances and features a self-locking drive mechanism for reliable, long-lasting performance.
Featuring high-grade brass posts fitted seamlessly into the housing, this enclosed tuner delivers exceptional wear resistance. The innovative stepped M6 flanged collar automatically centers the string post via the hollow bolt, eliminating tilting moment and removing the need for a stepped peghead bore.
Permanently lubricated with Schaller special grease for maintenance-free operation, this two-pin tuning machine maintains the same housing footprint as its single-pin predecessor with a 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) spacing from pins to string post center.
