Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed with high-precision CNC-machined parts and high-grade brass string posts, it ensures velvet-smooth, stable tuning and long-lasting durability.
Featuring the innovative stepped M6 flanged washer, this tuning machine provides reliable centering of the post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces strain on both the string post and rear mounting screw.
The M6 135 shares identical installation dimensions with its predecessor model, allowing for seamless direct replacement without guitar modifications. All enclosed tuners come permanently lubricated with Schaller special grease for completely maintenance-free operation.
