Medium handmade 6-string set for acoustic guitar from Rare series that delivers a low tension but loud and warm sound. These strings are made with phosphor bronze wires wound on hexagonal cores. They are a departure from the standard, good quality bronze string currently available... not necessarily better, but possessing a new, different and stronger “voice”. Guitars seem to benefit from a distinct improvement in tone, depth, and sustain with these strings. Players who want a fatter and louder sound, as well as a deeper bottom (who like to hear their guitars ring out) will appreciate the phosphor tone, sound, and feel. Gauges: .012, .016, .024, .032, .042, .054.
