Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets a high standard for closed tuning machines, combining historic design with modern precision engineering. Featuring a refined 1:18 gear ratio, it delivers ultra-precise, velvet-smooth tuning and exceptional pitch stability. Every component is CNC-machined and finished for seamless, self-locking operation.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine provides maximum wear resistance and zero backlash. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring a stepped peghead bore, eliminating tilting torque and protecting critical parts from excess pressure.
Each closed machine head is permanently lubricated with Schaller special grease for completely maintenance-free performance. Designed to retrofit original M6 footprints seamlessly, this tuning machine is built for long-lasting reliability and performance.
