Re: Hey Guitar builder guys ... Multi-piece bodies
How about doing your homework and give some science behind this claim?
Ok, you've misunderstood.....a few times in a row.
I thought I'd explained it in the last post.....you know the sentence where I said the only provable bit was that laminates are stiffer. Maybe you need to go back and read that one.
I was trying with that post you quoted to show that the 1-piece body thing was only a general opinion by using "thought", and that there
was no science backing it up. What you quoted was perhaps ambiguous as to where I stood on the matter.......but the last post wasn't.
As to those links you provided......nice, but its far from science/proof. Its more like an information flyer for an exhibition.
I accept you have exaggerated, and quite frankly I agree the neck is very important. But there are two ends to the string and each has to have a great anchor into nice wood/support......the whole is the sum of the parts and all that.
Stiffness and resonance is incredibly important. The whole shebang relies on the guitar structure as a whole maintaining the energy of the plucked string in a certain way. There are a lot of frequencies that are better off being dampened, and others which we really want.......either because they make the guitar work better with a typical amp, or that just what we expect/want to hear. The way the woods and hardware combine to perpetuate/absorb the energy in its various frequencies is the key to the whole thing.
Its mechanical physics......a complicated series of energy transfers in a system that is small enough that you add in the complications of reflections, phasing and coupling where the energy patterns seem to become infinitely more complicated the longer the note rings.
Glue joints are one of these interesting bits that really serve to complicate matters further. On the one hand you have something that is rigid which should transfer vibration very efficiently. But also you have something that might not be particularly organic in nature. Will that effect the way the energy passes between the two blocks???
There are endless possibilities here. For sure it won't act like just wood, and for sure there will be a loss as the energy transfers between the two bits via the glue. A lot of the animal glues are said to dry very hard....meaning (theoretically) a more efficient energy transfer. But its still not wood, and where two different bits of grain meet, the way that they vibrate in a very local sense (due to orientation and density) might be quite different - maybe this is why some bits of wood just don't work well together.
All in all it is a very complicated area......like trying to understand/explain the entire world's weather in a few short sentences. And like weather, there is no place that doesn't have any so you can test the effect of only 1 variable in isolation.
