D'Addario J4505C Pro-Arte Composite, single A5 string

Single 5th A string for the EJ45C set. EJ45C, normal tension, is D'Addario's best selling "composite" set, preferred for its balance of bold, yet warm tone, comfortable feel and dynamic projection.
Pro-Arté Composite strings feature an exclusive multifilament stranded core material which delivers a powerful, but warm tone which lasts 2-3 times longer than traditional classical strings.
