Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard for precision, stability, and smooth operation. Engineered with an improved 1:18 gear ratio, it delivers velvety and highly accurate tuning for modern guitarists. CNC-machined components with a self-locking drive ensure ultra-fine adjustment and long-lasting tuning stability.
Crafted with premium high-grade brass string posts fitted directly into the housing, this tuning machine provides maximum wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the hollow bolt, eliminating tilting torque and protecting the headstock without the need for step-boring.
Each closed tuning machine is permanently lubricated with Schaller special grease, making it completely maintenance-free. With identical mounting dimensions to its predecessor model, the M6 135 allows for seamless, direct replacement on existing instruments.
