Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation, driven by an improved 1:18 gear ratio. As an evolution of the iconic closed tuning machine introduced in 1966, this model incorporates refined mechanical innovations while maintaining classic performance and aesthetic appeal.
Precision CNC-machined components and high-grade brass string posts ensure long-lasting wear resistance and unmatched tuning stability. Each enclosed tuner is permanently lubricated with Schaller special grease, providing completely maintenance-free functionality across extended playing sessions.
Equipped with an innovative stepped M6 flanged washer, this system centers the string post securely through the threaded bushing without requiring step-drilled headstock holes. This design eliminates tilting torque and evenly distributes tension to protect both the post and mounting screws.
