Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for ultra-precise and smooth tuning stability. Built upon the legendary design originally introduced in 1966, this modern iteration incorporates advanced engineering and refined tolerances without compromising its classic pedigree.
Every component is precision CNC-machined and surface-treated, driven by a self-locking mechanism that guarantees consistent and sensitive operation. The solid brass string posts are accurately fitted into the housing to ensure optimal mechanical response and wear-free performance, lubricated for life with special grease for entirely maintenance-free reliability.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation by accurately centering the post via the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque and significantly reduces physical stress on both the string post and rear mounting screws.
