Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning comfort with its refined 1:18 gear ratio. As an evolution of the iconic closed tuning machine introduced in 1966, this model incorporates advanced design improvements while maintaining original mounting dimensions for straightforward replacement.
Precision CNC-machined components and high-grade brass string posts provide smooth, stable tuning with maximum wear resistance. All enclosed housings feature permanent lubrication with Schaller special grease, ensuring maintenance-free performance and long-term durability.
The innovative stepped M6 flanged collar reliably centers the string post without requiring stepped headstock drilling, effectively eliminating tilt momentum and taking strain off both the post and rear mounting screw.
