The low e, a and d strings don't sound like they once did. They sound like they are tuned down so you can't hear them very well, but they are not. here is the story of how this might have happened. My friends came over and we started to jam out. My guitar sounded fine before they came over. But then we started to jam out in my garage and it was pretty hot because I live in El Paso Texas. After we jamed out I took my guitar back to my room and it sounded as I mentioned above. What happened? It is a Ibanez RG 270DX in case this helps
