Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision engineering with an improved 1:18 gear ratio for smooth, accurate, and stable tuning. Built upon the legacy of the original 1966 design, all components are CNC-machined and finished to deliver sensitive handling and wear-free operation.
Featuring high-grade brass posts precision-fitted into the housing, the M6 135 provides exceptional tuning stability. An innovative stepped flange washer ensures straightforward installation and reliable centering without requiring stepped headstock drilling, effectively eliminating tilt torque.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, this tuning machine retains the identical mounting dimensions of its predecessor for direct, seamless replacement.
