Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. CNC-machined components with refined surface finishing ensure smooth, sensitive, and highly stable operation. Brass string posts fitted precisely into the housing guarantee long-term wear resistance and superior tuning stability.
Featuring the innovative stepped M6 flanged washer, this tuning machine centers the string post securely through the banjo bolt without requiring a stepped peghead bore. This intelligent design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
Permanently lubricated with specialized Schaller grease for completely maintenance-free performance, the M6 135 shares identical installation dimensions with its classic predecessor for direct, modification-free retrofitting.
