Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished, while the self-locking drive ensures smooth, sensitive, and stable string adjustment.
Featuring high-grade brass posts precision-fitted into the housing, these enclosed tuners provide wear-free longevity and exceptional tuning stability. The permanently lubricated internal mechanism requires zero maintenance thanks to high-grade Schaller special grease.
The innovative stepped M6 flanged washer centers the string post securely via the banjo bolt and eliminates tilting torque without requiring a stepped peghead bore. With identical installation dimensions to its classic predecessor, it offers a direct replacement for guitar upgrades.
