Schaller M6 Mini Guitar Tuning Machine
The Schaller M6 Mini guitar tuning machine delivers legendary engineering in a compact, lightweight format. Designed with an advanced 1:18 gear ratio, it provides exceptional tuning precision, smooth responsiveness, and outstanding comfort for 12-string guitars, smaller headstocks, and classic solid-body models.
Crafted with premium components, all string posts are precision-machined from high-grade brass and fitted seamlessly into the housing for maximum tuning stability and long-lasting wear resistance. Sealed construction with specialized Schaller permanent lubrication ensures fully maintenance-free, self-locking performance over years of continuous play.
Featuring the innovative stepped collar design with a 0.39-inch (10 mm) diameter, this tuner reliably centers the post without requiring stepped headstock drilling. This smart mechanism absorbs string tension and tilt torque, protecting both the string post and rear mounting screw from unnecessary strain.
