Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Engineered with an upgraded 1:18 gear ratio, it ensures velvet-smooth, highly sensitive, and reliable adjustments. Every component is CNC-machined and finished to exact tolerances for a durable, self-locking drive mechanism.
Crafted with premium brass string posts, each tuner is precisely seated within the housing to maximize wear resistance and sustain. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moment and relieving stress on mounting screws without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. Designed for seamless replacement and custom configurations, they provide robust performance for musicians demanding professional-grade hardware.
