Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers smooth, precise tuning with an improved 1:18 gear ratio. Designed with CNC-machined components and surface-finished parts, it utilizes a self-locking drive to provide consistent tuning stability and velvety responsiveness.
Crafted with premium brass string posts precisely fitted into the housing, this machine head offers durable, wear-free performance. The innovative stepped M6 flanged washer eliminates tilting torque by securely centering the string post without requiring stepped headstock drilling.
Featuring permanently lubricated internal components with Schaller special grease, the M6 135 is completely maintenance-free. It shares identical installation dimensions with previous generations, allowing straightforward, modification-free replacement on compatible guitars.
