Alright, I have a problem with my amp. when playing my tweeter seems to generate some kind of muddy fuzz, that increases while playing lower frequencies---->on my low B it is worse then on my high G. The noise seems to be coming from the tweeter, but I'm not sure. Aren't tweeters more into high frequencies then low ones, and therefore, shouldn't the noise increase while playing higher notes? Assuming the tweeter is blown, how about replacement? How much does a new tweeter cost? Is it hard to replace etc etc.
