i get where you're coming from, all i can say is that i spend a lot of time playing and recording in this room...the bare walls, egg crates, and plywood all have a different sound to my ears; the bare walls being the most unpleasant of the 3
Dude, repeat after me... RIGID FIBERGLASS
Egg cartons do less than jack shit. Sorry, but that's physics. If you can't find rigid fiberglass (try a heating & cooling place) you can substitute with rockwool (under the ROXUL brand) found at your local Home Depot. Cover with cloth & mount on your walls & in the corners. Stagger the mountings so you have alternate covered & bare patches. You should notice a MAJOR improvement.
