Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuning mechanisms, combining legendary heritage with state-of-the-art precision. Engineered with a refined 1:18 gear ratio, it delivers velvety-smooth and remarkably accurate tuning stability. Every component is CNC-machined to exacting tolerances and treated for enduring performance and wear resistance.
Featuring high-grade brass string posts precisely seated within the housing, this tuning machine eliminates backlash through its self-locking drive mechanism. The innovative stepped M6 flanged washer centers the string post securely over the banjo bolt, eliminating tilting moment and relieving pressure from both the post and rear mounting screws without requiring stepped headstock drilling.
Permanently lubricated with specialized Schaller grease for completely maintenance-free operation, the M6 Pin utilizes a two-pin mounting layout with a 0.39 in (10 mm) pin spacing and a 0.31 in (8 mm) pin-to-post distance. It offers versatile customization options to match your exact headstock configurations and performance preferences.
