Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 represents a legend in perfection, delivering an enhanced 1:18 gear ratio for velvety smooth, highly precise, and reliable tuning comfort. Engineered with the identical installation dimensions as its historic predecessor, it allows direct retrofitting and replacement on guitars without requiring instrument modifications.
Precision CNC-machined components with premium surface finishing and brass string posts guarantee exceptional tuning stability, long-term durability, and wear-free operation. Every enclosed tuner is permanently lubricated with Schaller special grease for completely maintenance-free performance across diverse playing conditions.
Featuring the stepped M6 collar washer with a 0.39 in (10 mm) diameter base, this mechanism reliably centers the string post without requiring stepped headstock drilling. This innovative design eliminates tilting moments and relieves structural pressure from both the post and the rear mounting screw.
