The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning stability with its refined 1:18 gear ratio. Designed with CNC-machined components and premium brass string posts, this closed machine head ensures velvet-smooth and backlash-free operation.
Featuring the innovative stepped M6 flanged washer, it eliminates the need for stepped headstock boreholes while securely centering the string post. High-grade Schaller special grease provides permanent internal lubrication for completely maintenance-free performance.
Built with identical mounting dimensions to its classic predecessor, the M6 90 allows for straightforward drop-in replacement on electric and acoustic guitars without requiring instrument modifications.
