Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Each component is CNC-machined to exacting tolerances and surface-finished, utilizing a self-locking drive mechanism to maintain consistent and precise string tension.
Equipped with high-grade brass string posts precisely fitted into the housing, these tuners ensure maximum tuning stability and wear-free performance. The specialized stepped M6 washer centers the string post securely through the banjo bolt, preventing tilt torque and eliminating the need for stepped peghead holes.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free reliability. The M6 180 fits directly into standard configurations for seamless upgrades and effortless installation on solid or slotted headstocks.
