Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine sets the standard for closed guitar tuning mechanisms, offering smooth handling and exceptional tuning stability. Designed with a precise 1:18 gear ratio, this model ensures refined, velvety-smooth tuning adjustments. Every component is CNC-machined and finished for consistent, self-locking operation.
Featuring high-grade brass string posts engineered seamlessly into the housing, the M6 delivers wear-free longevity and rock-solid pitch retention. The innovative stepped M6 flanged washer reliably centers the string post through the banjo bolt, eliminating tilting friction and reducing mechanical stress without requiring a stepped peghead bore.
Permanently lubricated with Schaller special grease, all internal mechanics are entirely maintenance-free over their lifespan. The standardized two-pin housing ensures direct compatibility with modern mounting patterns while maintaining legendary acoustic and functional performance.
