Great answer, silverwood. Can I ask you, the Bluthner I'm thinking of buying was made in 1984 and is all original i.e. strings, hammers, felts etc. I've heard that pianos generally need a major overhaul i.e. change of strings, hammers, dampers etc every 30 years. That would mean that all this work will probably need doing on this Bluthner, or is this not the case?
