Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. All components are precision CNC-machined and surface-treated to guarantee smooth, sensitive, and stable tuning performance with a self-locking drive mechanism.
Crafted with premium brass posts fitted into the housing, this tuning machine provides maximum tuning stability and long-lasting wear resistance. The sealed housing comes permanently lubricated with Schaller special grease, ensuring completely maintenance-free functionality over its entire lifespan.
Featuring the innovative stepped M6 flanged washer, this design centers the string post securely without requiring stepped peghead holes. This smart engineering eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screws for a reliable installation.
