Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and reliable tuning stability with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and high-grade brass string posts, it ensures smooth, friction-free operation and exceptional longevity.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. The design eliminates tilting moment and absorbs mechanical stress from both the post and rear mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 135 maintains the identical installation dimensions of its predecessor for effortless retrofitting and replacement.
