These would be easier to get and sell than smaller discs (and the secret formula disc shrinking varnish seems to keep evaporating before it can be fully tested), which is probably why there isn't a salesman's desk top demonstrator model of the benefits of tiny resonating membrane discs which, even though you can't see them, are so crucial to fine tone. They keep losing those tiny hammers used to activate the little disc for the demo to, which tends to spoil the effect. Then, of course, there are the bats to contend with if the frequencies get too high. Best to not go looking for trouble, I suppose. Ron N
