Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and velvety-smooth operation with its optimized 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-finished, and feature a self-locking drive mechanism that guarantees consistent, highly responsive, and reliable tuning stability.
Crafted with premium brass string posts precision-fitted into the housing, this enclosed tuner ensures maximum wear resistance and enduring performance. Every unit is permanently lubricated with Schaller special grease, rendering it completely maintenance-free across its lifetime.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) diameter base, the string post centers securely via the banjonut without requiring a stepped headstock bore. This design eliminates tilting torque and protects both the string post and rear mounting screw from unnecessary stress.
