The Schaller M6 90 guitar tuning machine delivers outstanding precision and velvet-smooth tuning comfort thanks to its refined 1:18 gear ratio. As the modern evolution of the legendary original sealed tuner, it incorporates precision CNC-machined components, high-grade brass string posts, and premium surface finishes for enduring tuning stability and wear-free operation.


Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation while reliably centering the post without requiring a stepped headstock bore. This intelligent design eliminates tilting torque and reduces strain on both the string post and rear mounting screws.


Each sealed tuner is permanently lubricated with specialized Schaller grease for completely maintenance-free performance. Designed with identical mounting dimensions to its predecessor, the M6 90 offers seamless retrofitting across classic and modern instruments.
