Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 represents the evolution of the legendary enclosed guitar tuner, setting standards for tuning precision and stability. Engineered with an enhanced 1:18 gear ratio, it delivers velvety-smooth and highly accurate adjustments. High-precision CNC-machined components and surface finishes ensure sensitive, uniform, and wear-free operation.
Crafted with premium brass string posts precisely fitted to the housing, this machine head offers maximum pitch stability and longevity. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moments, relieving stress on the rear mounting screw, and removing the need for stepped headstock boreholes.
Featuring permanent lubrication with Schaller special grease, the enclosed housing provides completely maintenance-free performance. It shares identical footprint dimensions with preceding models, allowing seamless, modification-free retrofitting on standard guitar headstocks.
