Glass or crystal over copper...

[sixbird]

Anybody ever try a glass or crystal over copper? Wonder how it turned out and how it sounded?

Thanks Tom...One day I'm going to have one made, if for nothing else than an experiment...

had a request for a  glass copper call was rather higher pitched ,,,when I first did it  figured it would be raspy but wasn't case ,, fellow that bought it was please with it ,, but like any combo of surfaces and sound boards you mess with the measurements of call and any thing is possible

Thanks man...Think there's anything that could get more rasp with that combo?
