Very much a beginner (I know were the notes are, some chords and can play simpler songs) My brother had this - http://www.guitarcenter.com/-i1149235.gc and I liked it quite a bit This is the one I WOULD get if it's at least close -... show more Very much a beginner (I know were the notes are, some chords and can play simpler songs)
