Bought a Epi Casino in July of this year had for a week it developed a rattle and a pop intermitant pop. Had gotton the special warranty from Guitar Center called them and they said it needs to go to gibson in Nashville. so after having for a week it goes away for 3 weeks to Nashville comes home and after a week devolops a rattle again. I understand it is more fragile than a solid body or semi hollow body but what the heck. Should a brand new hollow body guitar that I must say still sound awesome have a rattle. Gibson told me it was a loose pick up. Could this be the case again. I am a rookie having only been playing for 2 and a half years so I dont even know what it looks like inside on a P90 pick up. Does this sound familiar to anyone. ???
