In this video interview, James Bay talks about what strings he uses on his acoustic guitars. Starting at 4:49: "I've gone up to 13s recently, because I dropped down, I was on 12s, cause I’d go down a whole tone. I’ve been using some Ernie Ball strings recently, they’ve got a range called Earthwood strings, which I was enjoying…" The fact that he refers to the Ernie Ball Earthwood line and 13 gauge means he's using the Ernie Ball 2002 Earthwood 80/20 Bronze Medium Acoustic Guitar Strings.more
These strings seem to last pretty long which is great because I never have time to change guitar strings. Ernie Ball Earthwoods start out with a nice, even tone (not too bright/good heavy bottom), retain that tone and they hold up well to my violent right hand. I was told by an art teacher that I draw like I'm holding a hatchet and I kinda play guitar that way too sometimes. They're usually priced affordably.
