Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets the standard for closed-type tuners, combining legendary design with contemporary engineering. Featuring an improved 1:18 gear ratio, it delivers ultra-precise, velvety-smooth tuning alongside maximum tuning stability. All structural components are CNC-machined to exacting tolerances and treated with specialized permanent lubricant for maintenance-free operation.
Crafted with premium brass string posts fitted directly into the housing, the M6 Pin effectively minimizes mechanical wear over extended playing sessions. The innovative stepped flanged washer centers the string post securely through the banjo bolt, eliminating tilting torque and removing lateral pressure from both the post and rear mounting screws.
Engineered for effortless installation, the two-pin alignment system matches the exterior housing dimensions of previous single-pin iterations for streamlined upgrades. Its self-locking drive mechanics and rigid build provide musicians with reliable, stage-ready pitch accuracy across a versatile range of configurations.
