Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding tuning precision and velvet-smooth operation powered by an optimized 1:18 gear ratio. CNC-machined from premium components, each sealed unit features brass string posts accurately fitted into the housing for maximum tuning stability, wear resistance, and permanently lubricated maintenance-free performance.
Equipped with an innovative stepped collar design, this tuner centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This structural improvement eliminates tilting torque and relieves mechanical stress from both the post and mounting points, ensuring optimal longevity and flawless string tension handling.
Designed with standard dual-pin mounting, the M6 Pin offers exact housing compatibility with legacy Schaller pin models for effortless replacement. Engineered with precision engineering tolerances and self-locking drive mechanics, it guarantees stable, responsive tuning across demanding playing styles.
