Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine features a refined 1:18 gear ratio that delivers precise, velvety-smooth tuning operation and exceptional pitch stability. High-precision CNC-machined components and high-grade brass string posts ensure wear-free longevity and consistent performance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine reliably centers the string post via the banjo bolt, eliminating the need for a stepped peghead bore while preventing tilting moments and excess pressure on the mounting screws.
Featuring permanently lubricated internal gears with Schaller special grease, these enclosed tuners are completely maintenance-free and share identical installation dimensions with their predecessor models for straightforward drop-in replacement.
