Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and stability with an enhanced 1:18 gear ratio. Designed to set the standard for enclosed tuners, it ensures a smooth and accurate tuning experience for demanding guitarists.
Crafted with CNC-machined components and high-grade brass string posts fitted directly into the housing, this machine delivers wear-free performance and superior tuning stability. The self-locking drive and internal permanent lubrication using Schaller special grease ensure maintenance-free longevity.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, it centers the string post securely through the threaded bush without requiring stepped peghead holes. This smart design eliminates tilting moments and relieves pressure from both the post and mounting screws.
