Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. CNC-machined components and high-grade brass posts ensure durable, wear-free performance and reliable string tension support.
Featuring the innovative stepped M6 flanged washer, this tuner eliminates tilting torque and centers the string post without requiring stepped headstock drilling. Permanently lubricated with specialized Schaller grease, the sealed housing provides maintenance-free operation.
Built with identical mounting dimensions to its classic predecessor, the M6 135 enables straightforward drop-in replacement while maintaining exceptional tuning accuracy and longevity.
