Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark with its enhanced 1:18 gear ratio, delivering precise, velvety smooth tuning comfort and exceptional stability. All components are CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free operation.
Equipped with high-grade brass posts engineered precisely into the housing, this tuning machine provides maximum wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tipping torque and doing away with the need for a stepped headstock bore.
Featuring the exact installation dimensions of its classic predecessor, the M6 135 allows for seamless, direct replacement without modification. Its self-locking drive and premium craftsmanship ensure dependable tuning performance across diverse configurations.
