hi i have an ibanez acoustic guitar for about 2 months and lately i noticed that whenever i play a note on the 3rd fret of the high e string, it makes a very loud almost like a buzzing kind of sound compare to the other frets on that string. this is in standard tuning and all the other notes on that high e string is fine except when i play a note on the 3rd fret. it even sounds weird when i play the D chord u can hear that high e sound when you strum it. is it time to change the string or is it the guitar..or me?

if its the string, can someone recommend a good brand to get?
