Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents the evolution of an industry-standard closed tuning machine, engineered with a refined 1:18 gear ratio for exceptionally precise and smooth tuning stability. Built with CNC-machined components and premium surface finishing, it features a self-locking drive mechanism that delivers consistent, sensitive, and dependable performance.
Crafted with high-grade brass string posts precisely fitted into the housing, these tuners minimize mechanical wear and maximize tuning integrity. Every enclosed housing is permanently lubricated with Schaller special grease to provide a lifetime of completely maintenance-free operation.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt, eliminating the need for stepped headstock drilling while removing tilt moment and tension from both the post and rear mounting screw.
