To see is doing the tonerite thing would help out the sunburst guitar I stuck an aquarium air pump on the strings at the bridge. I let it run for a few days and then I did some tap testing of the top with a PC spectrum analyzer. The guitar top resonance was 203 Hz before doing it,
and 211 Hz after. Now whether the change was due to vibrating the top or not I am not sure. I did set up the guitar the same way both times, I would feel more confidant if I tested it before and left it in the same position the whole time till the second test. I will have to redo the test a number of times on different new guitars before I can say one way or the other. I would have to set up a computer in another room though as vibrating the top sounds annoying after a short period of time.
