Schaller M6 90 Guitar Tuning Machine

The Schaller M6 90 guitar tuning machine delivers outstanding precision and velvet-smooth tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original closed tuning machine established in 1966, this modern iteration incorporates advanced design enhancements while preserving its legendary reliability.
Crafted with CNC-machined components and high-grade brass string posts, every tuner guarantees exceptional tuning stability, smooth operation, and wear-free performance. The self-locking drive and permanent Schaller special grease lubrication ensure consistent, maintenance-free functionality over a lifetime of play.
Featuring the innovative stepped M6 flanged washer, installation is effortless and eliminates the need for stepped peghead boreholes. Sharing identical installation dimensions with its predecessor, it serves as a seamless, drop-in replacement upgrade for your instrument.
