These Black Diamond Black Coated Phosphor Bronze Acoustic Guitar Strings (600B Series) are designed to deliver warm, balanced acoustic tone with extended string life and a smooth playing feel.
Built using a 92/8 phosphor bronze alloy (92% copper, 8% tin), these strings produce a resonant low end with clear mids, making them well suited for fingerstyle and expressive acoustic playing. Each string is finished with a black protective coating that reduces finger noise, provides a consistent feel across the fretboard, and helps resist corrosion from sweat and hand oils.
The evenly applied coating supports uniform tension and response from string to string, while the black finish offers a subtle, understated aesthetic. With proper care, these strings can last significantly longer than standard uncoated phosphor bronze sets.

String Care
Install with care to protect the black coating, and wipe strings after playing to reduce buildup. Some visible wear over time is normal and does not affect performance.
