The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision, tuning comfort, and long-lasting stability. Engineered with an upgraded 1:18 gear ratio, it delivers an exceptionally smooth, accurate, and velvet-like tuning experience. Every component is CNC-machined with meticulous attention to detail and precision-fitted to eliminate backlash.
Featuring high-grade brass string posts and permanently lubricated internal gears with Schaller special grease, this enclosed tuner guarantees entirely maintenance-free operation and exceptional wear resistance. The self-locking drive mechanism ensures uniform feel and ultra-reliable pitch retention even during aggressive playing styles.
