Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuning mechanisms, featuring a refined 1:18 gear ratio for ultra-precise and smooth tuning stability. Built with CNC-machined components and self-locking drive technology, it ensures reliable and sensitive adjustments across diverse playing conditions.
Crafted with premium high-grade brass string posts fitted directly into the housing, this machine head prevents wear and maintains consistent intonation. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped peghead bore, eliminating tilting forces and reducing mechanical stress on mounting components.
Engineered for lifetime reliability, each closed housing is permanently lubricated with Schaller special grease for maintenance-free operation. Featuring standardized 0.39 in pin spacing, it is engineered for direct installation and replacement across modern and vintage guitar headstocks.
