What do we mean by a guitar "opening up"?

Most of the good research on guitar acoustics has been part of PhD theses in engineering departments, where the head has an interest in the guitar. Bernard Richardson as UWales/Cardiff is one such. The students learn to use all the nifty computer vibration modeling software and the accelerometers and such that go along with it, on their way to designing better airplanes or cars or whatever. No valuable patents have been encroached on, the students become proficient, and everybody benefits. The trick is to find a student who can be talked into doing such useless research. Maybe we need to raise some ourselves? ;)

In a conversation I had with Luthier Agostino LoPrinzi about 15 years ago in his workshop in Clearwater, Florida, he stated he could tell the personality/playing style of a guitarist that owned one of his guitars when he played the instrument at a later date: whether an aggressive player, timid, using the entire fretboard, etc. He had been building guitars, violins and ukeleles for over 40 years ,at that time, and certainly had developed a keen sense of acoustics in practicing his Art. An instrument made of wood theoretically should be effected by vibrations much as Turkish cymbals season with age and playing time. "Opening up?" Absolutely. Playing again . . . Rognvald P.S. I would use the analogy of a leather baseball glove when it is new and after it has been used for a season. They are certainly two different animals.

how much it would cost to analyse a bit of varnish in their RAMAN machine. Around £7,000 was the answer. That was a RAMAN machine at a university too. That's just a one off sample!

Yeah but the analysis comes with a really tasty soup.
