Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding tuning precision and velvet-smooth operation with its refined 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent, fine-tuned, and stable performance.
Crafted with premium high-grade brass string posts fitted precisely into the housing, these tuners provide maximum tuning stability and wear-free longevity. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, removing tilt torque and eliminating the need for a stepped peghead hole.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 135 maintains identical installation dimensions to its predecessor for direct replacement without instrument modifications.
