Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an upgraded 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, featuring self-locking drive mechanisms for delicate and reliable tuning stability.
Equipped with high-grade brass string posts engineered precisely into the housing, this machine head provides maximum wear resistance and pitch stability. The permanently lubricated enclosed design utilizes specialized Schaller grease to ensure completely maintenance-free performance throughout its lifespan.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, it centers the string post automatically through the banjo bolt and eliminates tilting torque without requiring stepped headstock peg holes.
