Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth and accurate tuning performance. Every component is CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent stability and sensitive adjustment.
Crafted with premium high-grade brass string posts precisely fitted into the housing, these tuners ensure zero play, maximum wear resistance, and exceptional tuning longevity. Each enclosed tuning unit is permanently lubricated with Schaller special grease, rendering it completely maintenance-free across extended playing cycles.
Featuring the innovative stepped M6 flanged washer, these tuning machines facilitate reliable centering through a 0.39 in (10 mm) base step without requiring stepped headstock drilling. This smart design effectively distributes mechanical tension and eliminates tilting torque from both the string post and rear mounting screw.
