Hi, First guitar I bought (and just started learning how to play). I bought a new acoustic guitar and I also bought some D'addario medium guage strings with it.

Is it all personal preference whether to change strings right away? Should a beginner even worry about such a thing ?
I wouldnt worry to much but the strings u have on it....If u hav a few months of playing under ur belt u can start worrying about ur tone and wat strings u use...for now just learn the basics.
