Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides velvety-smooth action and precise tuning control. Engineered with CNC-machined components and premium surface finishing, it incorporates a self-locking drive mechanism to deliver reliable tuning stability and sensitive adjustments.
Crafted with high-grade brass string posts precision-fitted into the housing, this tuning machine minimizes wear and maximizes performance longevity. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tipping torque, relieving pressure from the rear mounting screw, and removing the need for a stepped headstock bore.
Permanently lubricated with Schaller special grease, each enclosed unit remains completely maintenance-free throughout its service life. Designed with a standard 0.39-inch (10 mm) pin-to-pin spacing and a 0.31-inch (8 mm) spacing from pins to string post center, it ensures solid, dependable installation on compatible headstocks.
