Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners with its refined 1:18 gear ratio, delivering velvet-smooth action, precision, and reliable tuning stability. CNC-machined and finished to exact tolerances, each component features high-grade brass posts engineered for wear-free performance.
Featuring the innovative stepped M6 flanged washer, this tuner allows straightforward installation and reliable centering of the string post via the hollow bolt without requiring stepped headstock drilling. This smart design eliminates tilting moments and relieves mechanical stress on both the post and mounting screw.
All enclosed internal mechanisms are permanently lubricated with proprietary Schaller grease for lifelong, maintenance-free operation. Designed to match the exact mounting dimensions of previous generations, it serves as a seamless drop-in replacement or upgrade.
