The Schaller M6 180 guitar tuning machine sets an industry benchmark for closed-type tuners, combining legendary heritage with modern engineering. Featuring an upgraded 1:18 gear ratio, it delivers unmatched tuning precision, velvety smooth operation, and superior tuning comfort.
Every component is precision CNC-machined and surface-finished, featuring a self-locking drive and high-grade brass posts fitted seamlessly into the housing for maximum tuning stability and wear resistance. Permanently lubricated with Schaller special grease, each unit remains completely maintenance-free throughout its lifespan.
