Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with a refined 1:18 gear ratio, delivering velvet-smooth and highly accurate tuning stability. Building on the legendary original closed-housing design from 1966, this upgraded model features CNC-machined components with premium surface finishes for reliable, self-locking performance.
Crafted with premium brass string posts precision-fitted into the housing, the M6 180 ensures maximum wear resistance and zero backlash. The innovative stepped M6 flanged washer eliminates tilting torque and self-centers the string post reliably without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease, these fully enclosed tuning machines are completely maintenance-free. Designed for versatile configurations, the compact footprint fits standard modern headstocks and provides dependable instrument tuning for stage and studio demands.
