Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers legendary performance with advanced modern engineering. Featuring an improved 1:18 gear ratio, it ensures precise, velvety-smooth tuning stability and unmatched ease of adjustment. Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Equipped with high-grade brass string posts engineered for wear resistance, the M6 Pin incorporates a self-locking drive mechanism that guarantees lasting pitch stability. The innovative stepped M6 flanged washer centers the string post securely via the banjonut, eliminating tilting moment and removing stress from both the post and rear mounting screws without requiring stepped headstock drilling.
Designed with a dual-pin mounting base, this tuning machine provides a direct fit for standard 10 mm pin spacings. Its robust construction and refined mechanical tolerances make it an ideal upgrade for demanding players seeking professional tuning precision.
