I recall reading Thomas Knatt taught Al Carruth luthiery. I think that is a definite plus. I met Mr. Knatt several years ago (I am from the Boston) and tried out a flamenco guitar of his and was impressed. I would imagine his classical guitar is in the same ball park. He has to be close to 80 and I am not sure if he is still with us. People, on average, do live longer in MA so it is likely he may be with us. I do not think he has built any guitars recently--at least his website does not give that impression. If there is one floating about and it is a good guitar and you are looking to buy a good guitar I think you will do good with it.
