Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution of the closed tuning machine standard set in 1966. Featuring a refined 1:18 gear ratio, it delivers velvety-smooth action, precision, and reliable tuning stability for modern guitars.
Every component is precision CNC-machined and finished for smooth operation, paired with a self-locking drive and premium brass string posts precisely fitted into the housing for maximum wear resistance. All enclosed tuners are permanently lubricated with Schaller special grease, making them entirely maintenance-free.
The innovative stepped M6 flanged collar centers the string post securely via the banjo bolt, eliminating tilting moment and relieving pressure on the mounting screws without requiring stepped headstock drilling. This design allows seamless retrofitting while optimizing acoustic transmission and mechanical longevity.
