Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers state-of-the-art precision and tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original 1966 closed-gear design, this modern version features CNC-machined components with premium surface finishing and a self-locking drive for smooth, reliable, and slip-free tuning.
Crafted with precision-fitted brass string posts, these tuners ensure maximum tuning stability and wear-free performance over years of use. All enclosed mechanisms are permanently lubricated with Schaller special grease to remain completely maintenance-free.
Installation is streamlined thanks to the innovative stepped M6 flanged washer, which securely centers the string post via the banjo bolt and eliminates tilting torque without requiring a stepped peghead bore.
