After a gig, all the jacks on my 4x10 were messed up, so I went to the place where I purchased it, and they reccomended me to some guy. So now this fat lazy stoner has my cab, and he claims that the tweeter is blown. Now I hadn't noticed any such thing, and a friend of mine tells me that every time he's brought his cab for repairs, someome always says his tweeter is blown. So the question is, do such people commonly lie about tweeters being blown so they can rip people off? (seems like it would work more easily than other attempts at ripping people off) I realize this is a strange question, but any help would be greatly appreciated.
