Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuners, delivering smooth operation and exceptional tuning stability. Featuring a refined 1:18 gear ratio, it provides precise and sensitive adjustment for demanding musical applications.
Constructed with high-precision CNC-machined components and premium brass string posts, the M6 Pin utilizes a self-locking drive and permanent special grease lubrication for maintenance-free performance. The innovative stepped M6 flanged washer centers the string post reliably through the banjonut, eliminating tilting torque and protecting the headstock.
Engineered with a dual-pin mounting configuration, this tuning machine features a 0.39-inch (10 mm) center-to-center pin spacing and a 0.31-inch (8 mm) spacing from the pins to the post center for seamless installation.
