Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for exceptionally precise, velvety-smooth tuning and outstanding pitch stability. Precision CNC-machined components and high-grade brass string posts ensure wear-free operation and lasting reliability.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring a stepped headstock bore. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 135 shares identical installation dimensions with its predecessor model, allowing direct and effortless replacement on compatible guitar headstocks.
