Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an advanced 1:18 gear ratio, this closed tuner ensures smooth, precise adjustment and velvety turning action for demanding musicians.
All components are CNC-machined to exacting tolerances, with brass string posts fitted seamlessly into the housing to guarantee wear-free performance and superior durability. Permanently lubricated with Schaller special grease, the enclosed mechanism operates completely maintenance-free.
An innovative stepped M6 flanged washer eliminates tilting torque and centers the string post securely over the banjo bolt without requiring stepped headstock drilling. Retaining identical installation dimensions to its predecessor, it serves as a seamless replacement or premium upgrade.
