Gluey . So are you going to try different bracing patterns on the outside ? One picture of guitar vibrations showed areas across the top vibrating and if you stuck a brace in between those areas you would get a four brace top like my Aria. That was for nice high notes . I wish all that wobbly stuff could be put to some use .It all looks good but seems to stop there . Many violinists seem to be shocked if you ask about the wood in the bow vibrating .Pernambuco bow wood is especially good at vibrating . There is a Pernambuco Guitar somewhere on youtube. It has a wonderful sound and probably a Ferrari price too .
