Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, engineered with a 1:18 gear ratio for exceptionally precise and smooth tuning. Each tuner is crafted with CNC-machined components and high-grade brass posts to deliver lasting tuning stability and wear-free performance.
Featuring the innovative M6 stepped flanged washer, this tuning machine reliably centers the string post through the banlon screw and eliminates tilting torque without requiring a stepped peghead hole. Permanently lubricated with Schaller special grease, the sealed housing ensures completely maintenance-free operation.
Sharing identical mounting dimensions with its predecessor model, the M6 135 allows for direct retrofitting and replacement without guitar modifications.
