Interesting, thanks!
Do you

That's interesting. Every overtone crystal I have played
Hi
Indeed, there are processes for things like filter crystals that reduce the
(very) near by responses. There are approaches for things like SC’s to
take out the somewhat further out “bothersome” stuff.

Hi,
Hmm, such fiddeling could maybe also apply to nearby alternative modes
of the crystals, even if I guess it would be harder to do meaningful
dents on them.
Cheers,

Moin,
I have stumbled over another question I am unable to answer using the
tools I have available: Is there any fundamental difference in manufacturing
fundamental and overtone chrystals. Or to be more precise: is there an
optimization process during manufacturing that makes a crystal more
