Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. Continuing the legacy of the original closed-type design introduced in 1966, this updated version features refined CNC machining and premium brass string posts for superior tuning stability and wear resistance.
Equipped with an innovative stepped flanged washer with a 0.39 in (10 mm) base, this tuner reliably centers the post without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screw.
All internal components are permanently lubricated with Schaller special grease, ensuring maintenance-free performance. Precision-engineered for seamless operation, it offers a direct replacement for previous models while providing stable, sensitive adjustments.
