Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets high benchmarks for precision and tuning comfort with its refined 1:18 gear ratio. CNC-machined and surface-treated for maximum longevity, every component is engineered to deliver smooth, sensitive, and reliable tuning stability.
Equipped with high-grade brass posts precisely fitted into closed housings, these tuners feature a self-locking drive and permanent lubrication with Schaller special grease for entirely maintenance-free operation. The innovative stepped M6 flanged washer reliably centers the string post through the banjonut, eliminating tilting torque and simplifying headstock installation.
Designed with a dual-pin mounting configuration featuring a 0.39 in (10 mm) pin spacing, the M6 Pin delivers a direct drop-in replacement footprint for predecessor models while offering versatile configurations including standard, Locking, and TopLocking formats.
