Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and velvet-smooth tuning performance with its refined 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts fitted precisely into the housing, it ensures exceptional tuning stability, self-locking engagement, and wear-free operation.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post via the banjo bolt and eliminates tilting torque without requiring a stepped headstock bore. The assembly relieves mechanical pressure from both the post and mounting screws, protecting the integrity of your instrument's headstock.
Permanently lubricated with Schaller special grease for maintenance-free reliability, the M6 135 maintains identical installation dimensions to its predecessor for a seamless drop-in replacement on compatible guitars.
