Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. Designed with CNC-machined components and a self-locking drive, it provides smooth, uniform operation and dependable performance for electric and acoustic guitars.
Featuring high-grade brass string posts engineered for wear-free durability, this closed-gear tuner incorporates permanently lubricated Schaller special grease for completely maintenance-free operation. The innovative stepped M6 flanged washer ensures straightforward installation and precise axis centering without requiring a stepped peghead bore.
Built as a direct replacement for standard sealed guitar tuners, the M6 180 fits existing configurations seamlessly while eliminating tilting torque and reducing pressure on both the post and rear mounting screws.
