Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets a high standard for closed tuners, featuring an upgraded 1:18 gear ratio that delivers precise, velvet-smooth tuning and exceptional pitch stability. Every component is CNC-machined and finished to exact tolerances, driven by a self-locking mechanism for smooth, reliable adjustments.
Crafted with premium brass string posts fitted directly into the housing, this tuning machine provides maximum wear resistance and tuning reliability. The innovative stepped M6 flanged washer centers the string post securely over the threaded bushing, eliminating the need for a stepped peghead hole while removing tipping torque and pressure from the mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 180 can directly replace original M6 tuners without any modifications to standard headstocks.
