Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine represents a refined standard in closed tuning machines, engineered with a precise 1:18 gear ratio for smooth, velvety, and exceptionally accurate tuning. All components are CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent stability and sensitive adjustment.
Crafted with premium brass string posts fitted precisely into the housing, this tuning machine ensures maximum wear resistance and pitch stability. The stepped M6 flanged washer with a 0.39 in diameter eliminates tilting torque and centers the post reliably without requiring a stepped headstock bore, taking pressure off both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 180 easily replaces previous generations without headstock modifications. It delivers professional performance and flawless tuning integrity for discerning guitarists.
