So there's this new tail Piece manufacturer who Claims his Cello tail pieces are worth between 800 and 1200 $. Now, normally I would have a laugh at their Claims and the Price tag, but this guy has some big Name cellists promoting his tail pieces. He has a patent pending, though I wonder what about this design is worth a patent, as there seems to be nothing new about it, all done before, the Thing just seems to cut some weight. Has anyone tried These tail pieces?
