Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 tuning machine sets a high standard for enclosed tuners with its refined 1:18 gear ratio, delivering precise, velvety-smooth tuning and exceptional pitch stability. Built with CNC-machined components and high-grade brass string posts fitted precisely into the housing, it ensures wear-free and reliable operation.
Featuring the innovative stepped M6 flanged washer, this tuner simplifies installation and maintains solid, permanent axis centering. The integrated step on the base of the 0.4 in washer eliminates tilting moment and absorbs stress from both the post and the rear mounting screw, removing the need for a stepped peghead hole.
All enclosed housings are permanently lubricated with Schaller special grease for completely maintenance-free performance. Designed with identical mounting dimensions to its predecessor, the M6 135 allows for seamless, modification-free drop-in replacement on compatible guitars.
