Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and reliability. Engineered with an improved 1:18 gear ratio, it delivers ultra-smooth, fine-tuned operation and exceptional tuning stability. Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for maintenance-free performance.
Featuring high-grade brass string posts matched precisely to the housing, this tuning machine eliminates gear wear and backlash. The innovative stepped M6 flanged washer reliably centers the string post and eliminates tilting torque, relieving pressure from both the post and rear mounting screws without requiring stepped peghead drilling.
Equipped with a dual-pin mounting design with 0.4 in pin spacing, the M6 Pin ensures secure installation on compatible headstocks. Premium surface finishing and robust self-locking drive mechanics provide consistent tuning control across all playing styles.
