Great links and resources.
Rather than a DIY project (I already have too many) I brought it back for someone else to be challenged. It would have been a 4th mediocre guitar. So I am looking at a Marcassa laminate Martin with spruce top for $600+!!. It is set up and ready to go with no worries ( unless it shatters !?) It's made in Mexico which is a plus to me.
All I know is that carbon fiber cellos can also sound super.

I still have a soft spot for 'old' and 'real wood' but the sound of the Marcassa DX 1AE Martin - oh my.
