Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and smooth tuning comfort with an optimized 1:18 gear ratio. As the modern evolution of the legendary enclosed machine head first introduced in 1966, it features precision CNC-machined components and surface finishes that ensure long-lasting tuning stability.
Engineered for maximum reliability, each string post is crafted from premium brass and seated directly into the housing to eliminate play and wear. The enclosed mechanism comes permanently lubricated with specialized grease for completely maintenance-free operation over years of play.
Equipped with an innovative stepped flanged washer, this tuning machine simplifies installation by automatically centering the post and removing stress from both the shaft and mounting screws without requiring stepped headstock drilling.
