Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets an exceptional standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio for ultra-smooth and accurate tuning. Every component is CNC-machined to exacting tolerances and surface-finished, utilizing a self-locking drive mechanism that guarantees consistent stability and sensitive adjustment.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine delivers optimal wear resistance and maximum tuning integrity. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, preventing tilting and eliminating stress on the rear mounting screw without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 180 seamlessly retrofits previous models without modification. Its robust build and engineered internal geometry make it a premier choice for demanding musicians seeking ultimate performance.
