This is a dumb question, but is there anyway to remove the back panel to see the speakers? I just got the cab and it sounds awsome, more than i expected, but i want to make sure that i got the speakers i ordered. I removed the input jack and was able to see the Vintage 30's on top, but it is IMPOSSIBLE to look at the bottom speakers through that tiny hole. I just want to make sure that i got the G12H30's on the bottom. Sorry for the stupid question, and thanks in advanced.
