well from my understanding of acoustic instruments wood selection IS
important and tone DOES improve with age due to the drying and
hardness properties of certain timbers, that's why mahogony is such a
good choice, spruce too.
Here's something I posted to another group, you all may be interested.
1st off, Most musical instruments (guitars included) are not built out of
wood...it is all seasoned and, so long as you maintain about ~45%Rh, it will
neither get dryer nor wetter as it ages. Hence the popularity of humidifiers
Keep in mind, solid topped axes are built out of quarter sawn stock...the
single most expensive cut you can get ('cause the yield is so low)...they
age this stuff long and hard before it is sold and most shops have their
own aging rooms...they want it well seasoned before they put all the effort
of turning it into a guitar.
Does the wood have an impact on tone...on solid topped (non laminated)
steel string guitars, different woods do indeed sound different (all else
being equal)...this is easily verifiable, just play 'em. Spruce is different
from cedar which is different from Koa, which is different from Mahog,
etc...it's the old Indian versus Brazillian Rosewood argument or Sitka
versus Engelmann Spruce...even similar tonewoods have different
properties Obviously, as soon as you amplify them, you loose
some of that distinction and the biggest factors affecting the tone
will be the PU's/mic and amplifier...and that's not mentioning effects.
So solidbody electrics, may get some sustain from the wood density,
but the majority of the tone comes from the sound reinforcement
On the other hand, solid topped acoustic instruments may exhibit other
characteristics. The wood cells, after constant vibration over time,
get a little elastic (or perhaps broken) and, many people report that
sustained movement does cause an effect called "opening up".
Presumably, the vibrations should be equal or sympathetic to the top
resonance (tap tone) to get the full effect...obviously depending on the
bracing (thickness and finger distribution) and wood used, but generally
speaking, solid tops that have cells and grain running in the same
direction (not laminated, not flat sawn), have this facility. The vibration
is centered on the bridge, so if you want to artificially stimulate it,
need to work that into the equation.
There are many who have done (and are doing) research in this area.
Do a google on Left Brain Lutherie or drop by
and ask lots of questions.
The opinions, comments, and advice offered by me, are mine alone.
As such, they carry as much weight as a feather in a snow storm.
