Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for enclosed guitar tuning machines, featuring an advanced 1:18 gear ratio that provides silky-smooth, precise tuning action. Each component is CNC-machined to exacting tolerances and treated with a high-grade surface finish, while the self-locking drive mechanism ensures exceptional tuning stability.
Equipped with high-grade brass string posts engineered for wear-free performance, the M6 180 incorporates Schaller's innovative stepped flanged washer. This 0.39 in (10 mm) diameter washer centers the string post precisely through the banjo bolt, eliminating tilt and removing mechanical pressure from both the post and rear mounting screw without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these enclosed tuners offer seamless drop-in replacement for original M6 models without headstock modification.
