Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision guitar tuning with an advanced 1:18 gear ratio for smooth and accurate adjustments. High-grade CNC-machined brass string posts and components ensure dependable tuning stability, wear resistance, and long-lasting performance.
Featuring the stepped M6 collar washer with a 0.39 in (10 mm) base, this tuning machine centers the post via the banjonut and eliminates the need for stepped headstock holes. This design relieves lateral stress from the string post and rear fixing screw while preventing tilting.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free operation. Engineered for direct drop-in replacement on standard headstocks, it offers seamless integration without structural instrument modifications.
