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. CNC-machined components and high-grade brass string posts provide exceptional durability, precise adjustments, and dependable performance.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and solid centering without requiring a stepped peghead bore. This design eliminates tilting torque and protects both the string post and mounting screws from undue tension.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 shares identical mounting dimensions with its predecessor model, enabling direct drop-in replacement on compatible guitars.
