Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision instrument tuning with an upgraded 1:18 gear ratio for smooth, accurate adjustments. Originally setting the benchmark for closed-type tuners in 1966, this refined iteration combines vintage heritage with modern engineering advancements.
Each component is CNC-machined to exact tolerances and features high-grade brass string posts fitted directly into the housing for maximum tuning stability and wear resistance. The self-locking internal drive mechanism and permanent Schaller lubrication ensure velvet-smooth, maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring stepped peghead drilling. This structural improvement eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screws.
