Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and exceptional mechanical stability. Engineered with an upgraded 1:18 gear ratio, it provides velvety smooth adjustments and reliable tuning accuracy. All parts are precision CNC-machined and surface-treated, featuring a self-locking drive mechanism for stable, consistent performance.
Crafted with premium brass string posts fitted directly into the housing, this machine head minimizes wear while maximizing tuning retention. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on mounting components.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, this sealed tuner offers robust longevity and effortless operation. Built for solid headstocks and versatile guitar setups, it represents an advanced standard in precision instrument hardware.
