I bought it like 3 months ago. At first it was beautiful I’m new to guitar it sounded deep and good now it sounds quieter and dull. Also the low e string rattles if I hit it to hard not even that hard. It sounds different. Do I need new strings or what? Also the little black bag with the battery inside fell off including the tape holding it in place I superglued it back on the black wire isn’t in sight but you can see it hanging there. Anyway what could be the problems? I also bought an amp and a 60s telecaster so idk maybe something there
