Hey, Played a gig last night was really unhappy with the sound coming from my amp, checked it today, seems one of the speakers could be blown. I was playing just ghost notes to test and 3 of the speakers were vibrating(visibly moving) with the notes as per usual, and one wasn't. Is this a blown speaker, or possibly some wiring problems, whats the best solution? Can i get this particular speaker fixed or do i need to get a brand new one.... Thanks for any help, it's much appreciated!
