Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin represents the benchmark in closed guitar machine heads, engineered with a refined 1:18 gear ratio for velvety smooth, precise, and stable tuning. Every component is CNC-machined to exact tolerances, delivering durable self-locking performance and exceptional tuning stability.
Equipped with high-grade brass string posts precisely seated in the housing, these machine heads ensure wear-free operation. The stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moment and removing stress from both the post and mounting points without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 Pin utilizes a two-pin rear mounting configuration with a 10 mm center-to-center pin distance. Each unit is built to deliver unmatched reliability and legendary craftsmanship.
