They seem to. Very happy with this. Couldn’t really afford to spend more/enough to get a silver one, part or whole. This has a silver mouthpiece, at least. I had a Yamaha lined up, but after listening to some demo sound files, the Pearl had a much sweeter tone, so it won. It is more than good enough for my moderate ability.
Good practice for my asthmatic lungs, as well.
