I have this 1x12 widebody on order: http://www.mesaboogie.com/Product_Info/Guitar Cabinets/COMPACTcabs/WidebodyOB-1x12-LG.htm I was thinking it would be good to have an open back for what I do... no metal or heavy stuff - more rock/pop styles. But, if I wanted to experiment, would it be simple to close this back up? From the picture, it looks like it would be easy enough to add another half back to it. Anyone ever do this? Do you have trouble because it's two pieces instead of one? Could I get away with velcroing it on, or must use screws? Maybe there should be a very small gap so there is no vibration against the other cover piece? This is for experimentation with the sound, and also possibly as a solution for venues where I have the cab miked and facing me, and I need to kill the sound escaping out the back toward the audience. Thoughts?
