Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine features a precise 1:18 gear ratio that delivers exceptional accuracy and smooth tuning comfort. All components are high-precision CNC-machined and surface-finished, utilizing a self-locking drive mechanism to ensure consistent, responsive, and stable tuning.
Crafted with premium brass string posts precisely fitted into the housing, these tuners guarantee maximum tuning stability and wear-free operation. Every closed tuner is permanently lubricated with Schaller special grease, making it completely maintenance-free throughout its lifespan.
The innovative stepped M6 flanged collar with a 0.39-inch diameter ensures reliable installation and centering over the hollow screw without requiring a stepped headstock bore. This specialized design eliminates tilting torque and absorbs stress from both the string post and rear mounting screws.
