I have an old Marshall MG50RCD that my grandmother bought me back when I graduated from high school. I have not played it in a long time but I can't bring myself to part with it. I always loved the clean channel and I discovered at band volume that the clean channel has a very pleasing breakup to it that I found way better than the drive channel or any pedals I ran into it. I am guessing the worst part of this thing is the speaker. I am wondering if any of you guys have gutted old MGs and put JCM800 circuits in there?
