Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering velvet-smooth operation and exact tuning accuracy. Built upon the legendary enclosed tuner design established in 1966, this modern iteration incorporates CNC-machined components and high-grade brass posts engineered for maximum tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuner centers the string post securely through the banjo bolt and eliminates tilting torque without requiring stepped headstock drilling. Every enclosed unit is permanently lubricated with Schaller special grease, ensuring completely maintenance-free performance throughout its lifespan.
Designed for straightforward replacement and versatile installation, the M6 180 fits seamlessly across compatible solid and slotted headstock guitars. Its self-locking drive mechanism and precision-machined housing provide consistent tension and dependable tuning control for demanding players and builders alike.
