The Schaller M6 90 tuning machine delivers precision engineering with a refined 1:18 gear ratio, ensuring smooth and highly accurate guitar tuning. Designed with CNC-machined components and premium brass string posts, it provides maximum tuning stability, wear resistance, and reliable performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine enables effortless installation and solid centering of the string post without requiring a stepped headstock hole. The self-locking drive and internal permanent lubrication with specialized grease ensure completely maintenance-free operation.
Built to the standard mounting dimensions of its classic predecessor, the M6 90 allows for direct, modification-free retrofits. Its robust construction eliminates tilting torque and protects both the post and mounting hardware from unnecessary stress.
