The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio for ultra-smooth and accurate tuning. Crafted with high-grade CNC-machined components, it delivers superior tuning stability and velvet-smooth operation.
Equipped with premium brass string posts carefully fitted into the housing, this machine head offers exceptional wear resistance. Permanent internal lubrication with Schaller specialty grease guarantees a completely maintenance-free lifespan.
The innovative stepped M6 flanged washer ensures effortless installation and solid centering without requiring stepped headstock peg holes. This design effectively eliminates tilting torque and reduces mechanical strain on both the string post and rear fixing screws.
