Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry standard with an upgraded 1:18 gear ratio for velvety smooth, ultra-precise tuning comfort. Building on decades of legendary performance since 1966, this closed-gear tuner incorporates state-of-the-art enhancements without compromising its timeless character.
Precision CNC-machined components and high-grade brass string posts fitted seamlessly into the housing guarantee unmatched tuning stability, wear resistance, and self-locking precision. Each tuner is lubricated for life with specialized grease, delivering completely maintenance-free operation across years of demanding play.
An innovative stepped M6 flanged washer ensures effortless centering of the string post via the threaded bushing, completely eliminating tilt momentum and stress on mounting screws. With identical installation dimensions to its predecessor, it serves as a seamless, direct-fit replacement upgrade.
