Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed as an evolution of the iconic original introduced in 1966, it features precision CNC-machined components and high-grade brass string posts engineered for maximum tuning stability and wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation while reliably centering the string post via the threaded bushing. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screw without requiring a stepped peghead bore.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 180 is engineered to replace legacy models seamlessly. Its self-locking drive mechanism ensures consistent, sensitive, and stable tuning across all playing conditions.
