I was in a band with a loud fiddle player, and sitting at the steel guitar put my head about at the level of his amp. Ouch. So I stood my case up on its end, put my cowboy hat on top of it and draped my band jacket over the whole thing and had a baffle. He was offended. Oh, well. Studio baffles are pretty heavy, but a small, portable one that you could take to a gig would be a real handy thing to have.
