Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and surface-finished parts, it provides a self-locking drive for consistent and reliable tuning stability.
Featuring high-grade brass string posts meticulously fitted into the housing, this closed tuner ensures wear-free operation and maximum longevity. Every unit is permanently lubricated with Schaller special grease, making it entirely maintenance-free over its lifespan.
The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring a stepped peghead bore, eliminating tilting torque and relieving pressure from the mounting screws. It shares identical installation dimensions with previous models for direct, modification-free replacement.
