<DIV><FONT size=3> Actually you're possibly both a bit right & wr=
ong.
Wood that ages gets harder & that could equate to some increase in stiff=
ness
without an increase in mass. The tone <STRONG>perhaps</STRONG> changes
because of it but most likely its just a loss due to a change
in impedance.</FONT></DIV>
<DIV><FONT size=3> I bought some air dried Sitka a few years b=

It had air dried 20 years in a barn in the heat & cold of the central va=

Ca. It was rough cut for an eventual sailboat mast that never got
made.</FONT></DIV>
<DIV><FONT size=3> I had it resawed at a local mill th=

does a huge amount of custom work & the head guys comment was" that was =
some
hard wood". He couldn't believe it was spruce. He said there were sparks fly=
ing
off the band saw blade & stated that the nature of wood is to =
get
harder the longer it's dried. So take it for what it's worth.</FONT></DIV>
