Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original closed-type design introduced in 1966, this modern version incorporates extensive CNC-machined engineering refinements for high tuning stability.
Crafted with premium brass string posts and permanently lubricated with Schaller special grease, each unit operates smoothly and requires zero maintenance. The innovative stepped collar washer aligns the string post securely without requiring stepped peghead counterbores, effectively eliminating tilt torque.
Featuring dual rear positioning pins with a 0.39 in (10 mm) spacing and an 0.31 in (8 mm) post-to-pin center distance, this tuner guarantees solid headstock coupling. It comes complete with threaded bushings, stepped washers, and mounting screws for complete installation.
