I'm 53 years old, professional musician, and have been playing for a long timeacoustic guitars is my forte.... I've lived and worked in the States and Europe. Tried most brands thomann of acoustic guitar strings, especially bronzed wound, tho some brass as well. Since 1982, I ONLY use D'Addario's X-lites. No string responds better in my book staying in tune, life span, and brightness.
