It is obvious that a not-very-good guitar sounds better in the hands of a master, but do guitars change their sound over time depending on who plays them? I noticed that people were saying that they had went out and bought a guitar for performance that turned out to surprise them over the years. Would it make sense that a well-played guitar might improve its response, etc., even rise to the occasion? This is somewhat different, but I remember once in London talking to a friend of mine who was a piano student, and he said that the best job he had ever had was one he got playing a grand piano for some famous pianist (I forget who) who had just rebuilt his house and was going to be away for some time, and he wanted someone to "cure the walls" of his house. So my friend just went and played the piano for weeks to get the house used to the piano, and vice versa. If we are talking about responsive instruments, wouldn't they be likely to respond?
