Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth operation with an improved 1:18 gear ratio. Designed as an evolution of the legendary original sealed tuner, it features CNC-machined components and high-grade brass posts engineered for reliable, wear-free tuning stability.
Equipped with an innovative stepped flanged washer, this tuner reliably centers the string post via the banjo bolt without requiring stepped peghead drilling. 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 mounting dimensions with its predecessor for seamless drop-in replacement without instrument modifications.
