Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin sets a benchmark for closed guitar tuning machines with an advanced 1:18 gear ratio that provides precise and velvety smooth tuning performance. Precision CNC-machined components and a self-locking drive mechanism ensure consistent, sensitive, and stable string adjustment.
Crafted with premium brass string posts that are precisely fitted into the housing, this tuning machine delivers maximum tuning stability and wear resistance. All enclosed housings are permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, it eliminates tilting moment and pressure on the post and mounting points while ensuring effortless centering without requiring a stepped headstock bore.
