Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry standard for enclosed tuning mechanisms, engineered with an upgraded 1:18 gear ratio for velvety smooth, highly precise tuning. All components are CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation and exceptional longevity.
Crafted from premium brass, the string posts fit snugly into the housing to guarantee maximum tuning stability and wear resistance. The self-locking drive delivers uniform, sensitive adjustment, while the identical mounting dimensions of its predecessor make drop-in replacement completely seamless without requiring headstock modifications.
Featuring the innovative stepped M6 flanged washer, this design automatically centers the string post via the banjo bolt and eliminates tilt torque. This distributes mechanical pressure away from the string post and rear fixing screw, removing the need for a stepped hole in the headstock.
