Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the legendary benchmark for closed tuning machines, re-engineered for modern precision. Designed with an advanced 1:18 gear ratio, it delivers ultra-smooth, velvet-touch tuning response and unrivaled pitch stability.
Every component is CNC-machined to exacting tolerances and surface-finished for flawless mechanical operation. High-grade brass string posts are precision-fitted into the housing, while self-locking internal gears with permanent special lubricant guarantee lifetime maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through the banjobolt to eliminate tilting torque. It serves as a direct, modification-free replacement for previous M6 iterations, ensuring long-lasting performance for discerning players.
