Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. Designed with CNC-machined parts, it features high-grade brass posts precisely fitted into the housing for wear-free, reliable operation.
Equipped with the innovative Schaller stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped peghead bore. This advanced design eliminates tilting moments and relieves mechanical stress on both the post and mounting screw.
Featuring permanently lubricated internal components with Schaller special grease, the enclosed housing remains completely maintenance-free. It shares identical mounting dimensions with its predecessor model, allowing for direct replacement without instrument modifications.
