Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machines deliver legendary performance with a refined 1:18 gear ratio, ensuring velvety smooth adjustments and precise tuning stability. Each component is CNC-machined to exact tolerances, featuring brass string posts and high-grade surface finishing for long-lasting wear resistance.
An innovative stepped flanged washer centers the string post securely through the threaded bushing without requiring step-drilled headstock holes. This design eliminates tilting torque and reduces mechanical stress on both the post and the rear mounting screws.
Equipped with permanent internal lubrication using Schaller special grease, these sealed tuners remain completely maintenance-free. They retrofit seamlessly into standard headstocks, providing a dependable upgrade for professional and vintage instruments.
