Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers precise, velvet-smooth tuning performance with an upgraded 1:18 gear ratio. All components are CNC-machined to exact tolerances, featuring high-grade brass string posts engineered for maximum tuning stability, wear resistance, and long-lasting durability.
Equipped with the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. The sealed housing comes permanently lubricated with Schaller special grease for completely maintenance-free operation and smooth response.
Featuring the identical mounting dimensions of its predecessor model, the M6 135 allows direct replacement and upgrades on standard headstocks without modification.
