okay. catastrophe....looks like ive blown the tweeter in my nemesis 4x10 combo amp....not quite sure how though. ive been using pretty much flat eq settings, and recntly at failry loud volumes because of our rehearsing.....and when i play anything and put my ear up to the tweeter and pop a string/use distortion theres no sound emitting from it....any ideas what exactly has gone wrong? recently my amps been "feeding back" alot too if there is too much treble or gain.....i turned them down to fix it and doesnt appear to do anything. so now im left with an amp that just sounds plain muddy what should I do!?
