Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark for closed-type tuning mechanisms, engineered with high-precision CNC machining and an improved 1:18 gear ratio for velvety smooth, highly accurate tuning. Building on legendary heritage, it combines modern innovation with timeless reliability.
Featuring high-grade brass posts carefully fitted into the housing, this tuning machine ensures maximum tuning stability and wear-free operation. Every unit is permanently lubricated with proprietary Schaller special grease, providing completely maintenance-free performance throughout its lifespan.
The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring stepped peghead bore holes. This design effectively eliminates tilting torque and relieves mechanical stress on both the string post and rear mounting screws.
