Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability. Engineered with a refined 1:18 gear ratio, it delivers an ultra-smooth, velvet-like tuning experience and exceptional accuracy. All components are CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent performance.
Crafted with premium brass string posts fitted precisely into the housing, the M6 Pin ensures maximum wear resistance and rock-solid pitch retention. The innovative stepped M6 flanged washer centers the string post reliably via the banjo bolt, eliminating tilting torque and removing pressure from both the post and the rear mounting screws without requiring stepped headstock drilling.
Permanently lubricated with specialized Schaller grease, these enclosed tuning machines remain completely maintenance-free over their entire lifespan. Designed with identical housing dimensions to legacy single-pin predecessors, they provide straightforward mounting and rock-solid reliability for demanding players.
