Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine features a refined 1:18 gear ratio that provides velvety-smooth operation, pinpoint tuning accuracy, and long-lasting stability. CNC-machined components with a self-locking drive ensure sensitive adjustment, while high-grade brass posts fitted into the housing eliminate wear and maintain rock-solid pitch.
An innovative stepped flanged washer centers the string post securely through the hollow screw without requiring stepped peghead drilling, eliminating tilting moments and reducing mechanical stress on mounting screws. Each sealed housing comes permanently lubricated with Schaller special grease, delivering completely maintenance-free performance.
Engineered for effortless retrofit compatibility, this tuning machine drops directly into headstocks configured for classic M6 footprints without structural modifications. Precision manufacturing and robust engineering make it an ideal replacement or upgrade for discerning guitarists seeking uncompromising tuning reliability.
