Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 tuning machine delivers high-precision performance with an advanced 1:18 gear ratio, ensuring smooth and accurate tuning stability for electric and acoustic guitars. Each component is CNC-machined to precise tolerances, featuring surface-treated finishes and self-locking drive mechanisms that eliminate slippage and backlash.
Constructed with premium brass string posts fitted directly into the sealed housing, the M6 180 offers long-term durability and frictionless movement. All internal components are permanently lubricated with Schaller specialized grease, providing completely maintenance-free operation across years of continuous playing.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through the headstock without requiring stepped peghead drilling. This design absorbs lateral string tension and back-screw pressure, protecting the mechanism and preserving maximum tuning consistency.
