Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability. Engineered with a refined 1:18 gear ratio, it delivers velvety-smooth, highly sensitive tuning and reliable retention. Every component is CNC-machined to exacting tolerances and features a self-locking drive for frictionless, consistent adjustments.
Crafted with premium brass string posts fitted accurately into the housing, these tuners ensure maximum durability and complete wear resistance. The innovative stepped M6 flanged washer centers the post securely through the threaded bushing without requiring step-drilling into the headstock, effectively eliminating tilting torque and protecting critical mounting points.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these closed-construction machine heads combine classic heritage with state-of-the-art engineering. They provide uncompromising performance and tuning stability across diverse playing conditions.
