Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning comfort with its refined 1:18 gear ratio. All components are high-precision CNC-machined and surface-finished, utilizing a self-locking drive mechanism to ensure smooth, delicate, and dependable tuning stability across all applications.
Crafted with premium high-grade brass posts precisely fitted into the housing, the M6 90 guarantees maximum tuning stability and wear-free performance. Closed housing units are permanently lubricated with Schaller special grease, making them completely maintenance-free over their entire lifespan.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) diameter base, this machine head reliably centers the string post without requiring step-drilled headstocks. This design eliminates tilting moments and relieves mechanical pressure on both the string post and rear fixing screw.
