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 a self-locking drive deliver consistent, sensitive, and reliable string tuning for modern and vintage instruments alike.
Crafted with premium brass string posts precisely fitted into the housing, this enclosed tuner features permanent lubrication with Schaller special grease for entirely maintenance-free operation. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped peghead bore holes.
Maintaining the exact mounting dimensions of its classic predecessor, the M6 135 allows for seamless, modification-free replacement on compatible guitar headstocks while eliminating tilt torque and taking pressure off both the string post and rear fixing screw.
