Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine delivers exceptional tuning precision and stability, building upon the iconic closed-tuning legacy established by the original M6 in 1966. Featuring a refined 1:18 gear ratio, these tuners ensure an ultra-smooth, delicate, and precise tuning experience.
Every component is CNC-machined to exact tolerances and surface-finished for flawless mechanical operation. High-grade brass string posts are precision-fitted into the housing to guarantee wear-free performance and superior pitch stability, while permanent internal lubrication with Schaller special grease provides completely maintenance-free longevity.
Installation is streamlined with the innovative stepped M6 flanged washer, which reliably centers the string post via the banjo bolt without requiring stepped peghead drilling. This thoughtful engineering relieves mechanical stress from both the post and rear mounting screws, ensuring long-lasting durability.
