as a example of how wood gains better tone and quality through the years NO violin made today by anyone with any manufacturing method they could use will ever sound or be as valuable as a Stradivarius, the wood he used is gone there is no more ... much but not quite as important is the wood used by the old Keller shells and early vintage drum shells I have a picture of 5 guys i think standing on a rogers shell could that be done today? maybe i do not know but the older growth wood is much many times denser than the wood grown today and dats da fact Jack!
