Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an exceptional standard for closed-type tuners, featuring an upgraded 1:18 gear ratio for remarkably precise and smooth tuning stability. Built with CNC-machined components and high-grade brass posts precisely fitted into the housing, it ensures wear-free operation and reliable performance.
Equipped with the innovative stepped M6 flanged washer, this tuning machine enables effortless installation while centering the string post directly via the banjo bolt. This intelligent design eliminates tilting moments and relieves mechanical pressure from both the post and the rear mounting screw without requiring stepped peghead holes.
All internal components are permanently lubricated with Schaller special grease, providing completely maintenance-free functionality. The compact housing design allows seamless drop-in replacement on standard headstocks without structural modifications.
