Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning accuracy and smooth operation, featuring an upgraded 1:18 gear ratio. CNC-machined components and premium brass string posts ensure superior stability, precise adjustments, and extended wear resistance.
Equipped with Schaller's innovative stepped flanged washer, this machine head simplifies installation by centering the post via the hollow bolt without requiring a stepped peghead bore. This design effectively eliminates tilting torque and relieves mechanical stress on both the post and mounting screw.
With identical installation dimensions to its predecessor, the M6 135 allows direct drop-in replacement on existing instruments. Permanently lubricated with Schaller special grease, each enclosed unit provides long-term, completely maintenance-free performance.
