Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Engineered with precision CNC-machined components and high-grade brass posts, it provides maximum stability, wear-free performance, and a self-locking drive mechanism.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock hole. This design eliminates tilting torque and reduces mechanical stress on both the post and mounting screws.
Each sealed unit is permanently lubricated with Schaller special grease for completely maintenance-free functionality. Built to legendary standards, the M6 180 seamlessly retrofits traditional installations while offering superior modern mechanical refinement.
