Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original 1966 design, this closed-type tuning machine combines classic aesthetics with modern CNC-milled engineering and surface-finished components for self-locking, stable performance.
Crafted with high-grade brass string posts fitted precisely into the housing, these tuners ensure lasting wear resistance and maximum tuning stability. Each enclosed machine head is permanently lubricated with specialized Schaller grease, providing completely maintenance-free operation throughout its lifespan.
Featuring the innovative stepped M6 flanged washer, this tuner centers the string post reliably via the threaded bushing without requiring stepped peghead drilling. This functional design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
