Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the pinnacle of closed tuning machine engineering, delivering unmatched precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, ensuring consistent, sensitive, and stable tuning through a self-locking drive mechanism.
Equipped with solid brass string posts precisely fitted into the housing, these machine heads provide maximum tuning stability and wear-free performance. Permanent lubrication with Schaller special grease guarantees completely maintenance-free operation across the lifespan of the hardware.
Featuring the innovative stepped M6 flanged washer, installation is simplified while securing reliable post centering via the banjo bolt. This specialized design eliminates tilting moments and relieves mechanical stress from both the post and rear mounting screws without requiring stepped peghead counterbores.
