Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and smooth operation through its high-precision 1:18 gear ratio. Engineered with CNC-machined components and high-grade brass posts, it offers maximum tuning stability and wear-free performance for solid headstocks.
Equipped with an innovative stepped M6 flanged washer, the tuning machine seats securely without requiring a stepped peghead bore, eliminating tilt torque and protecting both string post and rear mounting screws. Each sealed housing is permanently lubricated with Schaller special grease for completely maintenance-free reliability.
Featuring a dual-pin mounting design with a 0.4 in (10 mm) pin spacing and 0.3 in (8 mm) post-to-pin distance, this tuner provides precise centering and direct installation. Complete mounting hardware is included for straightforward assembly.
