So as the title says the grill-cloth on my ampeg svt 15e cab isn't secured properly and is rattling against the cab. It is just the top portion of the grill-cloth that is rattling. I took of the grill and found that it was slightly warped, I tried putting new velcro fasteners on but it didn't help. Is there anything I can really do other than playing without the grill-cloth? I know you can order new ones from flip-tops but I really don't want to have to do that if its not necessary.
