Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for enclosed tuners, combining legendary design with modern precision engineering. Equipped with an upgraded 1:18 gear ratio, it delivers ultra-smooth, delicate, and highly accurate tuning stability for exceptional performance.
Precision CNC-machined components and high-grade brass string posts ensure wear-free longevity and a self-locking drive mechanism. Sealed with Schaller specialized permanent grease, the housing provides completely maintenance-free operation under demanding playing conditions.
Featuring the innovative stepped M6 flanged collar, this tuner eliminates the need for stepped headstock drilling while properly centering the string post. This advanced design relieves mechanical tilt torque and pressure from the mounting components to ensure rock-solid tuning stability.
