I am considering getting the device that JLD Guitars sells (as recommended in a recent thread) and the owner asked me to look inside the guitar and describe the bracing there. I've tried looking in with a dentist's mirror, but I don't see anything. Apparently the braces are too far in.

Does anyone know how to do this?

I can see the braces on the underside. Would they be symmetrical with those under the soundboard?
