My usual practise room is in my garage, my battered, falling apart garage. Whenever I play in there I get this UGLY and airy sound that I don't get when I play in other rooms/bedroom or outside. The roof is made out of very old slate like material and is literally just falling apart, there are lots of old carpets and cupboards against the walls. It is a pretty large room, roof is pretty low. The question is, could all of this really effect my sound and playing quality?
