I have an Aguilar GS 212 and last night, with the tweeter at about halfway up, I noticed that the tweeter made a distorted sound when I really dug in playing fingerstyle on the G string (I was playing pretty aggressively). The sound was not there when I turned the tweeter off, so if there is any issue I am pretty sure it's with the tweeter. Playing with normal touch everything sounds fine. I was playing through a GK 700RB-II head, which as some of you may know has pretty crisp highs. Do I have a blown tweeter, or is the distortion I heard normal? I'm not sure if distortion is the right word; it was sort of like a loose flapping sound, if that makes any sense.
