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 and highly accurate tuning stability. Building on the iconic closed-housing design established in 1966, this upgraded model features CNC-machined components with a self-locking drive mechanism for dependable performance.
Crafted with premium high-grade brass string posts fitted precisely into the housing, the M6 180 ensures maximum wear resistance and enduring reliability. All closed machine heads are permanently lubricated with Schaller special grease, making them completely maintenance-free throughout their operational life.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch diameter, installation reliably centers the string post via the hollow bolt without requiring stepped peghead counterbores. This design eliminates tilting moments and relieves stress from both the string post and rear mounting screw for optimal durability.
