Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets an industry standard for sealed tuners, engineered with a refined 1:18 gear ratio for ultra-precise and smooth tuning response. Built with CNC-machined components and high-grade brass string posts fitted precisely into the housing, this tuning system ensures superior tuning stability and wear-free performance.
Featuring the innovative stepped M6 collar washer, this tuner allows effortless installation while maintaining solid axis centering without requiring a stepped peghead bore. This design eliminates tilting torque and reduces direct mechanical stress on both the string post and rear mounting screws for extended longevity.
All closed mechanics are permanently lubricated with proprietary Schaller special grease, rendering them completely maintenance-free. The self-locking drive delivers sensitive, even adjustments suitable for high-performance acoustic and electric guitar setups.
