Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Engineered with high-precision CNC-machined components and surface finishing, its self-locking drive ensures smooth, delicate, and dependable tuning stability across all playing conditions.
Crafted with premium brass string posts fitted seamlessly into the housing, these tuners provide exceptional wear resistance and long-lasting tuning performance. The stepped M6 flanged washer reliably centers the string post through the banjonut, eliminating tilting moment and relieving stress on mounting hardware without requiring stepped headstock drilling.
Featuring identical installation dimensions to its classic predecessor, the M6 135 serves as a direct drop-in replacement requiring no instrument modifications. Every enclosed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation over its lifespan.
