Hey guys I have a peavey vypyr 30 amp..I was wondering if it would be ok to put a cover on the back? It sounds better, but I don't want to hurt the speaker..will/can that get messed up?

I never quite understood why some companies opened the back of their combo's and other closed them. To me, there is more bass response overall as opposed to an "open back" design.

If you are playing alone(no band accompaniment) or with a band. At normal bedroom volumes, its great, but at band practice, you may get "mudded" out. In other words, your tone will compete with the bass player and you will be drowned out by his tone.
