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 velvety-smooth operation through an advanced 1:18 gear ratio. Each component is CNC-machined to precise tolerances and finished to perfection, ensuring dependable self-locking performance and lasting pitch stability.
Equipped with high-grade brass string posts engineered seamlessly into the housing, these tuners eliminate play and provide long-term wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock holes, relieving excess mechanical stress from both the post and mounting screw.
Featuring factory-sealed, maintenance-free Schaller specialized grease lubrication, the M6 135 delivers durable and consistent performance. Designed with identical mounting dimensions to its predecessor, it serves as a seamless drop-in upgrade or replacement for modern and vintage instruments alike.
