Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin sets a refined benchmark for enclosed guitar tuning machines, delivering legendary design updated with modern precision. Engineered with a smooth 1:18 gear ratio, it provides velvety, ultra-precise tuning response and exceptional tuning stability. Each component is CNC-machined to exacting tolerances and factory-lubricated with specialized grease for completely maintenance-free operation.
Crafted with premium high-grade brass string posts, the M6 Pin ensures zero wear and solid acoustic energy transfer directly to the headstock. The self-locking internal drive mechanism and precision-fitted string posts maintain consistent tension across all strings, eliminating slippage and backlash during aggressive playing.
Installation is streamlined and reinforced through the innovative stepped M6 flanged washer. The 0.39 in (10 mm) stepped base centers the string post securely through the threaded bushing without requiring step-drilled headstock holes, eliminating tilt torque and protecting both the post and the rear mounting pins from stress.
