Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry standard for closed tuning machines, combining timeless design with modern engineering. Featuring a precise 1:18 gear ratio, it delivers velvety-smooth action, exact micro-tuning, and exceptional tuning stability. Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for maintenance-free operation.
Equipped with high-grade brass string posts and a self-locking drive mechanism, the M6 135 prevents backlash and resists wear over years of heavy use. The innovative stepped M6 flanged washer ensures straightforward installation and reliable post centering without requiring a stepped headstock bore, effectively eliminating tilting moments and reducing mechanical stress on mounting screws.
