Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the refined evolution of the original legend that set the global benchmark for enclosed tuners in 1966. Engineered with a precise 1:18 gear ratio, it delivers ultra-smooth action, exact adjustments, and exceptional tuning comfort for high-performance instruments.
Every component is CNC-machined to exacting tolerances, featuring high-grade brass posts and a self-locking drive mechanism that guarantees lasting pitch stability and zero play. All enclosed housings are permanently lubricated with proprietary Schaller grease, providing completely maintenance-free operation across years of demanding use.
Featuring the innovative stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post directly through the threaded bushing without requiring stepped headstock drilling. This design eliminates tipping torque and relieves direct mechanical stress from both the post and rear mounting screws.
