Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 tuning machine delivers high tuning stability and smooth mechanical performance for guitars with standard headstocks. Built with high-precision CNC-machined parts and a self-locking drive mechanism, it ensures sensitive, even, and consistent tuning adjustments.
Featuring an optimized 1:18 gear ratio, this model offers fine-increment accuracy. The brass string posts are precision-fitted into the sealed housing, which is permanently lubricated with Schaller specialized grease for completely maintenance-free operation.
The integrated stepped flanged washer reliably centers the string post through the banjonut, eliminating tilting torque and removing direct stress from both the post and the rear mounting screw.
