Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth operation with an improved 1:18 gear ratio for precise and velvety tuning. Built upon the legacy of the original 1966 closed-housing design, this updated model incorporates modern CNC manufacturing for enhanced durability and performance.
Featuring high-grade brass string posts precisely fitted into the housing, the M6 135 guarantees exceptional tuning stability and wear-free longevity. The innovative stepped M6 flanged washer centers the post reliably via the hollow screw, removing tilt torque and eliminating the need for a stepped peghead hole.
All closed mechanics are permanently lubricated with proprietary Schaller grease for entirely maintenance-free operation. Engineered with the identical installation dimensions of its predecessor model, it allows for direct drop-in replacement without modifying the headstock.
