A few years ago a Ken Parker interview was released and in it he stated the importance of woods used to make guitars
"every object has a fundamental resonant frequency... When a builder starts to build an instrument, the first thing he or she does is start listening to the material."
"If you’re making a handmade instrument, you find the perfect piece of wood, you dry it out for a long time, you apply your considerable chops to it and you come out with a damn nice neck that stays straight with a nice fret job, if everything goes well."
"There’s stuff that’s happening inside the material – the way it bounces, the way it deforms and returns to shape pretty much on a microscopic level, all determines how the material is going to respond. "
"Yeah, the neck, the stiffnesses and mass at the end of the neck (peghead) and the neck-to-body union, whatever that is – those things have a huge affect on the way that the instrument can respond and conserve energy, which is what sustain is all about – the conservation of energy. The energy has to go somewhere. If the string’s vibration is absorbed by the body of the guitar then we don’t have sustain. Physics again, but around the shop we playfully refer to each other as guitar scientists."

My guess is that you would find:
Inability to have a truss rod in the neck
Fret board that absorbs
Body that doesn't resonate
Flat uninspiring tone
No sustain
Potential warping as it slowly dries out
But I may be wrong...
