Light RARE Phosphor Bronze Acoustic Strings are a departure from the standard, good-quality bronze string currently available not necessarily better, but possessing a new, different, and stronger voice. Hand-carved archtops, dreadnoughts, and good steel string acoustic guitars of rosewood, maple, and mahogany benefit from a distinct improvement in tone, depth, and sustain with a fatter, louder sound and a deeper bottom. • MSKU RPM-12 • UPC 600781000796
