[gitarro]

Although a luthier should get better at his craft over time and introduces over time improvements which may have an effect on power or volume or tone, whether he builds a great guitsr or merely a good one o even an average one at any point of his career depends a lot on many factors, some or even many of which may be outside his control. For instance I have played 4 guitars made by one of the greatest luthiers recognised universally by even other luthiers, and ony one of those was a world beater of a guitar. Two were "merely" good while one was decidedly average when the luthier experimented with a wood hoice that he would not use again. All of them were built within a period of about 6-8 years from each other. I have no data fro his more recent guitars but I gave no reason to believe a different result will eventuate.
