Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, combining legendary heritage with modern precision engineering. Featuring an upgraded 1:18 gear ratio, it ensures exceptionally smooth, fine, and accurate tuning stability for electric and acoustic guitars.
Every component is CNC-machined to exact tolerances, featuring precision brass posts and a self-locking drive mechanism that guarantees wear-free performance. The permanently lubricated internal gears utilize proprietary Schaller grease for lifelong, maintenance-free operation.
Equipped with an innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring stepped headstock boreholes. It features identical installation dimensions to its predecessor, allowing for seamless direct-replacement upgrades.
