Hi this is varun. im a beginner .. have been playing since 2 months... i use a Hobner Jumbo Acoustic guitar. 2 of my guitar strings have broken so have to change the strings. I went to a music shop but they dont have Hobner strings. The salesman there suggested me to use D'Addario strings or Blue Nickle strings but the strings are quite costly( 450 & 475) so i have a question whether it wl be suitable to use these strings for my guitar or will it make it sound better? plz help
