Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for closed-type tuning machines, featuring a precise 1:18 gear ratio for exceptionally smooth and stable tuning. Engineered with CNC-machined components and high-grade brass posts, it guarantees long-term durability and pitch stability.
Featuring the innovative stepped M6 flanged washer, this tuner allows straightforward installation and reliable centering of the post without requiring stepped headstock peg holes. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screws.
Permanently lubricated with Schaller special grease, these maintenance-free tuners share identical installation dimensions with previous M6 models, making them a seamless drop-in replacement or upgrade.
