Well, these carbon cellos sound pretty nice, but they do not sound the same. It is much more powerful than a wooden one. It has not that "wooden" character.
A good comparison is the Bach Suites CD (4 CDs!) by Josephine van Lier. She recorded the suites on 4 instruments. A normal one, a baroque cello, a carbon and piccolo. Very, very interesting.
www.josephinevanlier.comThanks for this link cello fan, it is very interesting. The carbon cellos sound very different. I wouldn't say bad, just different. Plus, to hear one solo is quite subjective, to be sure..
I wonder what an entire section, or even an entire ensemble of carbons would sound like? My guess is that it would be LOUD for sure, but that soft warm glow we're all accustom to with string ensembles, would be missing.
