Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard for closed tuning machines, combining timeless design with modern engineering. Featuring a refined 1:18 gear ratio, it ensures precise, velvety-smooth tuning action and uncompromised pitch stability for any playing style.
Crafted with premium CNC-machined components and high-grade brass string posts, every unit is built for wear-free durability. The self-locking internal drive and permanent internal lubrication with Schaller special grease deliver completely maintenance-free operation over a lifetime of use.
Installation is straightforward thanks to the stepped M6 flanged washer, which centers the string post securely without requiring stepped headstock drilling. This innovative design eliminates tilting torque and reduces mechanical strain on both the post and rear mounting screws.
