Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and velvet-smooth operation with its refined 1:18 gear ratio. Designed to set the benchmark for closed guitar tuners, it combines classic engineering heritage with modern precision manufacturing.
Every component is CNC-machined to exacting tolerances, featuring high-grade brass posts fitted seamlessly into the housing. A self-locking drive mechanism and premium lifetime grease lubrication guarantee maintenance-free performance, wear resistance, and long-term tuning stability.
An innovative stepped M6 flanged washer ensures effortless installation and precise post alignment without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screws.
