Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth operation. Featuring an advanced 1:18 gear ratio, this precision-engineered tuner allows for exceptionally fine, velvet-smooth adjustments while maintaining rock-solid pitch stability across all playing styles.
Every component is precision CNC-machined and surface-finished to ensure lasting durability and reliable self-locking performance. High-grade brass string posts are fitted into the housing with extreme precision, eliminating mechanical play, minimizing wear, and providing long-term tuning reliability without maintenance thanks to Schaller special grease permanent lubrication.
Equipped with the innovative stepped M6 flanged washer, installation is streamlined while eliminating headstock tilt torque. This design perfectly centers the string post through the banjo bolt without requiring stepped headstock drilling, protecting both the post and rear mounting screw from unnecessary structural strain.
