Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for precision, comfort, and tuning stability. Engineered with a refined 1:18 gear ratio, it delivers velvety-smooth and remarkably sensitive adjustment for electric and acoustic guitars. Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for entirely maintenance-free operation.
Crafted with premium brass string posts fitted precisely into the housing, this tuning machine provides maximum wear resistance and rock-solid pitch retention. The self-locking drive ensures consistent performance across demanding playing conditions, while high-grade surface finishing provides lasting durability.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch (10 mm) base, the string post centers securely through the banjo bolt without requiring a stepped headstock bore. This intelligent design eliminates tilting torque and significantly reduces physical stress on both the post and rear mounting assembly.
