Re: Just had a rather interesting experience with a yamaha 62
It needs to be said that brass is an alloy of copper AND tin, CSM_J, anywhere from about 65% to 85% copper, depending on all that yellow brass, gold brass, red brass stuff. It has always been so. The addition of tin is not new. The reliance on alloys with more tin, the AS300 for example, is to make it strong yet inexpensive, for less metal is used overall. Find an older Martin, for example. Thick brass and heavy; more copper, greater molecular density, and it can't can't be overblown with a metal link 17* and a #6 reed. The AS300 sound , well, tinny, and distorts the moment you think about playing loud. Mr. Saxman, maybe this is an example of a stopped clock telling the right time twice a day. But I think not. My model 62 is from 1983, and is an almost perfect accoustical device, albeit one complete devoid of soul and character. I rely on it, but I don't love it.
