Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined tuning precision and smooth operation with an advanced 1:18 gear ratio. CNC-machined to exacting tolerances, every component features premium surface finishing and a self-locking drive mechanism that maintains consistent tension and superior pitch stability.
Built with high-grade brass string posts engineered for wear resistance, each closed tuner is lubricated for life with specialized Schaller grease for completely maintenance-free performance. The innovative stepped M6 flanged washer centers the string post reliably through the banjo bolt, preventing tilt momentum and relieving strain on the mounting screw without requiring stepped peghead holes.
Designed for straightforward replacement without modifications, the M6 180 seamlessly upgrades standard sealed headstock configurations. Its precision-engineered enclosed casing ensures lifelong durability and rock-solid intonation across high-demand playing conditions.
