Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and comfort with an upgraded 1:18 gear ratio. CNC-machined components and high-grade brass string posts provide smooth operation, precise adjustment, and long-term tuning stability.
Featuring the innovative stepped M6 flanged washer, this tuner centers the post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and protects both the string post and rear mounting screw from unnecessary stress.
Each closed machine head is permanently lubricated with specialized Schaller grease for maintenance-free reliability. Engineered as a direct retrofit for classic M6 models, it installs seamlessly on standard guitar headstocks.
