Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision and tuning comfort with an upgraded 1:18 gear ratio. Designed to preserve the legacy of the original closed-type M6 introduced in 1966, this model features high-precision CNC-machined components and surface finishes that ensure smooth, sensitive, and stable tuning.
Crafted with premium brass string posts precisely fitted into the housing, the M6 135 ensures maximum tuning stability and wear-free operation. The self-locking drive and internal permanent lubrication using Schaller special grease provide completely maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, the tuning machine centers the string post securely through the banjo bolt without requiring a stepped peghead bore. It matches the exact installation dimensions of its predecessor for seamless replacement without instrument modifications.
