Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for smooth, velvety precision and exceptional tuning stability. Built with CNC-machined components and high-grade brass string posts, it ensures wear-free longevity and consistent performance.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring stepped headstock drilling, effectively eliminating tilt and relieving stress from both the post and rear mounting screw. All closed gears are permanently lubricated with proprietary Schaller grease for entirely maintenance-free operation.
Featuring the exact installation dimensions of its predecessor, the M6 135 allows direct replacement and upgrades on standard solid or slotted headstocks without modification.
