How can I be sure I got what I paid for? I picked up a G1 soundwave at a yard sale. It seems like the real thing and has no rub sign as well. I also paid a pretty penny for it. I want to open it and make sure the markings are on it, but it is sealed and I know if I do it, I am going to ruin it if it is real. Any ideas what I should look for? I am going to get pics on here as soon as I can. Tomorrow most likely.
