Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning systems, offering an upgraded 1:18 gear ratio for exceptionally precise and smooth tuning stability. Every component is CNC-machined to exacting tolerances, featuring self-locking mechanics that deliver consistent, sensitive adjustment under high string tension.
Equipped with high-grade brass string posts engineered seamlessly into the housing, this machine head provides maximum tuning integrity and wear-free operation. The innovative stepped M6 flanged washer ensures effortless centering and secure installation directly into 10 mm peghead holes without requiring stepped counterbores, effectively eliminating tilting torque on the post.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 Pin utilizes a two-pin rear mounting configuration with a 10 mm center-to-center pin spacing. Each standard set includes threaded bushings and flanged washers, engineered to preserve flawless tone and reliable performance.
