Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability. Engineered with a refined 1:18 gear ratio, it provides exceptionally smooth, accurate tuning response and effortless pitch adjustments. Every component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for completely maintenance-free performance.
Crafted with premium brass string posts precisely fitted into the housing, the M6 Pin ensures maximum durability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the hollow screw, removing unnecessary pressure from both the post and fixing screw while eliminating the need for a stepped peghead bore.
Designed with standard rear locating pins featuring a 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) post-to-pin center distance, this tuning machine drops directly into compatible headstocks for reliable, rock-solid installation and performance.
