Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined and finished to deliver smooth, sensitive, and reliable operation with a self-locking drive mechanism.
Crafted with premium brass string posts precision-fitted to the housing, this machine ensures tuning stability and long-lasting durability. The innovative stepped M6 flanged washer centers the string post firmly via the banjo bolt, preventing tipping torque without requiring stepped peghead drilling.
Featuring permanently lubricated internal gearing with Schaller special grease, the enclosed housing is completely maintenance-free. It shares the identical installation footprint of previous M6 models for seamless retrofit mounting.
