Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a benchmark for closed guitar tuning systems, delivering precision and effortless tuning stability. Engineered with an upgraded 1:18 gear ratio, it ensures precise, velvet-smooth adjustment and durable performance. Every component is CNC-machined and surface-treated to guarantee smooth, reliable operation with self-locking drive mechanics.
Crafted with premium brass string posts fitted directly into the housing, these tuners offer superior wear resistance and maximum pitch retention. The stepped M6 flanged collar reliably centers the string post via the hollow bolt, eliminating tilting moments and taking mechanical stress off the post without requiring a stepped peghead bore.
Featuring permanent lubrication with specialized grease, each sealed unit remains completely maintenance-free over its entire lifespan. The design incorporates a dual-pin configuration with a 0.39 in (10 mm) pin spacing and 0.31 in (8 mm) post-to-pin distance, engineered to fit precise specifications across modern guitar models.
