I was watching Jeff Ocheltree's YouTube video of John Bonham's kit. When he hits the 16" tom, there's a definite pitch transition of about a minor third. Can anyone explain how the heads interact to produce this?
I know that it's a coated Ambassador on the bottom and a 2 ply coated Emperor on the top and it's pretty clear that he tunes them higher on the bottom and lower on the top.
What I'm hoping for is a detailed discussion of the process from the strike to the final decay including the way the weight difference between the top and bottom head plays into it etc etc. Basically, really geek out on the details.
