Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines legendary design with advanced modern engineering. Built with a precise 1:18 gear ratio, it ensures ultra-smooth, accurate tuning and exceptional tuning stability. CNC-machined components and self-locking drive mechanisms provide smooth, wear-free performance for any playing style.
Featuring high-grade brass string posts engineered for precision fit within the housing, the M6 Pin delivers remarkable durability. The innovative stepped M6 flanged washer reliably centers the string post through the banjo bolt, preventing tipping forces and eliminating the need for stepped headstock drilling.
Each closed machine head is permanently lubricated with proprietary Schaller special grease, making the entire assembly completely maintenance-free. Designed with standard 0.39 in pin spacing, these tuning machines provide a flawless direct upgrade for modern and vintage instruments alike.
