Very true Bobert - sometimes on the same guitar even. My other resonator, a Republic Miniolian bought by mail order, sounded very thin and tinny when I first played it, making me think I'd made a pretty big mistake buying it. After a few hours playing though,it warmed up considerably and now gives a warm, rich sound. I reckon it must be the cone "bedding in". I think you are right - there's a lot of room for improvement on some resonators via a good setup or just plain "playing in".
