Thanks again for the replies, I really appreciate your advice on this everyone.
So, heres what the party of the first part has to say about this body;
"Hello, the body is definitely Koa, it is my area of expertise (I've been working in the high end acoustic guitar manufacturing industry for almost 30 years). The wood is softer than Alder or Ash, or Maple and you can see proof of this looking at the indent from the neck plate on the back of the body. The Koa is not flame AA Koa, but flat sawn. Really the body feels nothing like a Maple, Alder or Ash body. Hope this clears this up,"
What say ye?
