my acoustic still has the same strings from when i bought it. they are not old but i hate the medium gauge and want something light like ernie ball slinkys. i dont think ernie bal makes acoustic strings but i may be wrong. what is a string similar to those i could use. i dont like elixirs or d'addarios (sp?). ive also heard the ernie balls are usually suitable for acoustic and electric but i dont want to risk it. and help?
