Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-finished, and permanently lubricated with Schaller special grease for maintenance-free operation. High-grade brass string posts fit precisely into the housing to provide maximum tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged collar, this tuner installs seamlessly and centers the post firmly without requiring a stepped peghead bore. This design eliminates tilting moments and relieves mechanical stress from both the post and rear mounting screws. Dual rear alignment pins maintain a 10 mm center-to-center spacing for secure placement on compatible headstocks.
Crafted to the highest engineering standards, the M6 Pin is engineered for smooth, responsive adjustment and unwavering performance across solid headstock instruments. Package contents include banjo bolts, flanged washers, and M2.2 x 9.5 mounting screws for complete installation.
