Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution in closed tuner engineering, combining classic design with precise modern manufacturing. Featuring an upgraded 1:18 gear ratio, it delivers ultra-smooth, fine-tuned calibration and exceptional tuning stability. High-precision CNC machining and high-grade brass posts ensure smooth, wear-free performance over years of play.
An innovative stepped M6 flanged washer streamlines installation and reliably centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screws. Every enclosed unit comes permanently lubricated with specialized Schaller grease for lifelong, maintenance-free operation.
Engineered as a direct replacement for previous iterations, the M6 180 mounts seamlessly without guitar modification. Whether chosen in standard, Locking, or TopLocking configurations, these premium machine heads offer dependable performance and superior string retention for discerning guitarists.
