Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuning mechanisms, featuring a precise 1:18 gear ratio for smooth and accurate tuning comfort. High-precision CNC machining and premium surface finishing ensure velvety, consistent operation and long-lasting tuning stability.
Equipped with high-grade brass string posts engineered seamlessly into the housing, these tuners minimize wear and maximize reliability. The innovative stepped M6 flanged washer reliably centers the string post through the banjonut, eliminating tilt torque and the need for stepped headstock drilling.
Permanently lubricated with Schaller special grease, each enclosed unit is entirely maintenance-free. With identical mounting dimensions to its predecessor, it serves as a direct drop-in replacement without requiring headstock modifications.
