Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and velvety-smooth operation with its improved 1:18 gear ratio. All components are CNC-machined to exacting tolerances, finely surface-finished, and permanently lubricated with Schaller special grease for maintenance-free reliability.
Crafted with high-grade brass string posts engineered directly into the housing, this machine head provides maximum tuning stability, wear resistance, and sensitive pitch adjustment. The self-locking internal mechanism prevents slippage under rigorous playing conditions.
Featuring the innovative stepped M6 flanged collar with a 0.39 in (10 mm) diameter base, it reliably centers the string post without requiring stepped peghead counterbores. This design eliminates tilting torque and reduces mechanical stress on both the string axis and rear mounting screw.
