Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, combining legendary design with refined modern innovations. Featuring an upgraded 1:18 gear ratio, it ensures precise, velvet-smooth tuning and exceptional pitch stability across all playing conditions.
Every component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for entirely maintenance-free operation. High-grade brass string posts are meticulously fitted into the housing to eliminate wear and maximize vibrational transfer to the headstock.
Installation is straightforward thanks to identical footprint dimensions matching earlier models and the innovative stepped M6 flanged washer. This washer self-centers the string post securely through a 10 mm (0.39 in) hole, absorbing mechanical stress and eliminating the need for stepped headstock drilling.
