I have an epiphone acoustic an AJ200 mahagony guitar. I got it during a lightning deal in 2011 from amazon. Good sound good average guitar but I don't think it is sold anymore since I couldn't find it online now. I have a problem with it buzzing on the last two strings. When u press the last two strings, it press on 4 frets causing a dead sound. Anybody knew how to fix this. A little background of what happen was that I put the guitar on a guitar stand in my room that was airconditioned for a month and that just happened. any idea what happened? thank you. I came from the equator and it is my first time moving to Indiana and so I am not sure how I am suppose to take care of my guitar since there is a difference in temperature.
