Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning machines, combining historic craftsmanship with advanced engineering. Featuring an upgraded 1:18 gear ratio, it ensures precise, velvet-smooth tuning and exceptional pitch stability across a wide variety of playing conditions.
Every component is CNC-machined to exacting tolerances, with brass string posts fitted directly into the housing to guarantee wear-free operation. The self-locking internal drive mechanism promotes consistent and sensitive adjustments, while lifetime lubrication with specialized Schaller grease ensures entirely maintenance-free performance.
An innovative stepped collar washer simplifies installation and securely centers the string post without requiring a stepped peghead bore. This design eliminates tilting moments and relieves mechanical stress from both the post and rear mounting screws for long-lasting reliability.
