Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets the benchmark for closed guitar tuning machines with an upgraded 1:18 gear ratio that provides velvety-smooth tuning precision. All components are CNC-machined to exacting tolerances and surface-finished to ensure consistent, stable operation through a self-locking drive mechanism.
Crafted from premium brass, the string posts fit precisely into the housing to maximize tuning stability and virtually eliminate mechanical wear. The integrated stepped M6 flanged washer centers the string post securely without requiring stepped peghead drilling, absorbing lateral forces and protecting mounting screws.
Permanently lubricated with Schaller special grease, these maintenance-free tuning machines offer drop-in replacement capability for original M6 models, delivering exceptional durability and reliable performance for discerning guitarists.
