Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning stability, continuing a legendary closed-gear design established in 1966. Engineered with a refined 1:18 gear ratio, it provides smooth, nuanced, and reliable string tuning across diverse playing conditions.
Every component is CNC-machined from premium materials, featuring high-grade brass string posts engineered for maximum wear resistance. The sealed housing is permanently lubricated with Schaller special grease, ensuring maintenance-free performance throughout its lifespan.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base, this tuner reliably centers the post via the banjonut without requiring stepped headstock drilling. This smart design eliminates tipping moments and distributes pressure evenly away from both the post and rear mounting screw.
