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 tuning. CNC-machined components and high-grade brass string posts ensure exceptional tuning stability, self-locking drive functionality, and long-term wear resistance.
Featuring an innovative stepped flanged washer, this machine head centers the post securely through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces strain on both the string post and rear fixing screws.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 180 offers drop-in compatibility for direct replacement and upgrades on standard guitar headstocks.
