Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed tuning machines, combining timeless design with a precise 1:18 gear ratio for smooth, accurate, and comfortable tuning. All components are CNC-machined and finished to exact tolerances, supported by a self-locking drive mechanism that delivers consistent tuning stability.
Equipped with solid brass string posts precisely fitted into the housing, this machine ensures wear-free longevity. The innovative stepped M6 flanged washer centers the string post securely via the threaded bushing, eliminating tilt torque and protecting against mechanical strain without requiring stepped peghead drilling.
Permanently lubricated with specialized grease, each sealed unit remains completely maintenance-free over its entire service life. The housing design allows for seamless replacement and retrofitting on standard guitar headstocks.
