Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning comfort with its refined 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-treated, and powered by a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine provides maximum tuning stability and wear-free operation. The closed housing design is permanently lubricated with Schaller special grease, ensuring dependable, maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, it eliminates the need for stepped headstock holes while reliably centering the string post and reducing pressure on mounting screws. It shares identical mounting dimensions with legacy models for a seamless, drop-in replacement.
