Sorry … been otherwise occupied today
1. Rod makes a good point: I think a much more ‘focused’ test would be to use the same dimensions, and let the weight be whatever it is.
2. YouTube audio is hopelessly inappropriate for a test like this
3. I would rather start by comparing the behaviour of three simple rectangular ‘plates’ of timber, of equal dimensions, in a simple modal analysis test. [but of course I worked for a vibration test-house. not a custom guitar components supplier]
