Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an upgraded 1:18 gear ratio, this closed-gear tuner ensures ultra-smooth and sensitive operation. Each component is precision CNC-machined and permanently lubricated with proprietary grease for maintenance-free performance.
Crafted with premium high-grade brass posts fitted seamlessly into the housing, the M6 135 offers superior wear resistance and rock-solid pitch retention. The stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting friction without requiring stepped headstock drilling.
