Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin sets an industry benchmark for closed guitar tuning machines, engineered with a refined 1:18 gear ratio for velvet-smooth, high-precision tuning. Each component is CNC-machined to exacting tolerances and surface-finished to ensure consistent, highly sensitive, and stable operation with zero backlash.
Crafted with premium brass string posts precisely seated inside the housing, these tuners deliver outstanding tuning stability and wear-free longevity. The innovative stepped M6 flanged washer eliminates the need for stepped headstock holes, centering the string post directly through the banjo bolt to remove tilting moment and reduce strain on mounting components.
Equipped with permanent Schaller special grease lubrication, these sealed machine heads operate completely maintenance-free across extended use. The dual-pin mounting configuration matches original vintage housing dimensions while securing the tuner firmly against the headstock.
