Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability, building upon the legendary legacy of the original closed-housing tuner. Engineered with a refined 1:18 gear ratio, it ensures ultra-smooth operation and precise pitch adjustment for demanding musicians.
Crafted with premium CNC-machined components and high-grade brass string posts, this tuning machine provides maximum wear resistance and consistent performance. The permanently lubricated internal mechanism utilizes specialized Schaller grease to ensure entirely maintenance-free reliability over years of use.
Featuring the innovative stepped M6 flanged washer, the unit enables straightforward installation and continuous center alignment without requiring stepped headstock drilling. This smart design eliminates tilting torque and effectively absorbs string tension to safeguard your instrument's headstock.
