Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth operation with an upgraded 1:18 gear ratio. Engineered as the modern evolution of the legendary original sealed tuning peg, it offers unmatched tuning comfort and exceptional stability.
Every component is CNC-machined to exacting tolerances, featuring high-grade brass string posts and permanently lubricated sealed housings for maintenance-free longevity. The self-locking drive mechanism ensures uniform, sensitive, and stable tuning adjustments across all performance conditions.
Featuring the innovative stepped M6 flange washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt. This thoughtful design eliminates tilting moments and relieves lateral stress from both the post and rear mounting screws while maintaining identical footprint dimensions for hassle-free replacement.
