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. All components are precision CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning performance.
Crafted with premium brass string posts precisely fitted into the housing, this machine head provides maximum tuning stability and wear-free operation. The enclosed housing is permanently lubricated with Schaller special grease, rendering it completely maintenance-free over its entire lifespan.
Featuring the innovative stepped M6 flanged washer, it centers the string post securely via the threaded bush without requiring a stepped headstock bore. This design eliminates tilting torque and relieves mechanical stress from both the post and rear mounting screw.
