Jazz9, Don't get "improved sound" and "improved feel" confused with better playing. Removing the lacquer from your horn will not make you play any better... only practice can do that! However, lots of guys take the lacquer off their horns, or buy horns without lacquer to start with, simply because it helps them find the personal tone they are looking for. Removing the lacquer can "free" the metal of the horn and allow it to resonate more naturally. Giving a darker tone usually sought after in the jazz world.
