About the upper panel.. How do you plan to make this work with your neck block? Would you cut the block short (by the thickness of the panel) and glue the top of the block to the panel or would you cut the panel around the neck block and glue directly to the top?
Also if you plan on using flat panels on the upper soundhole edge, have you given any consideration to making a larger patch to double the entire area around the soundhole? You can then eliminate the finger braces around the soundhole. I've used this approach on my last 3 guitars and I've really taken to that method. Just thought I'd mention it...
Cheers,
Chad
EDIT: I just realized you said you were NOT planing on adding the panel patches.
