I had some guy tell me years ago that your weight/fat content/build would affect the tone of your guitar because of how it could resonate differently on a fat person vs muscular. I thought this was another wack-a-doo theory like Eric Johnson and his rocking chairs, but I could see how it makes sense. I am on the more pleasantly plump side of life, but playing electric guitar I could see how actually feeling the vibration of instrument in my core could make things easier to feel. I have a bandmate who said since he started a more physically demanding job and lost a bunch of weight, he can feel his acoustic playing so much more and it inspires him to sing and perform better (on the nights he's not hammered, I think he has actually stepped it up a notch). Thoughts?
