Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for precise and velvety smooth tuning performance. Precision CNC-machined components with a self-locking drive ensure sensitive, consistent, and exceptionally stable tuning retention.
Crafted with premium brass string posts precisely fitted into the housing, these tuners deliver maximum tuning stability and wear-free operation. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilt torque and the need for a stepped peghead hole.
Permanently lubricated with Schaller special grease, each closed tuner is completely maintenance-free and engineered for long-lasting reliability. The housing design features a dual-pin configuration with a 0.39 in center-to-center pin spacing for solid alignment on compatible headstocks.
