Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed guitar tuning machines with its refined 1:18 gear ratio, offering precise, velvet-smooth tuning and exceptional pitch stability. High-precision CNC-machined components and high-grade brass string posts fit seamlessly into the housing to eliminate wear and ensure consistent performance.
Equipped with an innovative stepped M6 flanged washer, this tuner allows effortless installation while keeping the string post firmly centered without requiring a stepped peghead bore. This design effectively absorbs tipping torque and relieves pressure from both the post and the rear mounting screw.
Permanently lubricated with specialized Schaller grease for maintenance-free operation, the M6 180 directly replaces original M6 models without modification and is available in multiple locking and button configurations.
