Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark for precision, tuning stability, and reliability. Featuring an advanced 1:18 gear ratio, it ensures an ultra-smooth and accurate tuning process. High-precision CNC machining and surface refinement guarantee consistent, delicate adjustments with self-locking functionality.
Constructed with premium brass string posts precisely fitted into the housing, the M6 180 delivers exceptional wear resistance and long-lasting durability. The innovative stepped M6 flanged washer centers the string post securely via the banjonut, eliminating tilting moment and removing stress from both the post and rear mounting screw without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease, all sealed components remain completely maintenance-free over extended use. Engineered to directly replace previous M6 models without headstock modification, this tuning machine combines classic legacy design with modern high-performance engineering.
