I am into the idea of concert toms but I don't have any. I have been toying with the idea of taking my bottom heads off but only for recording. It seems like concert toms can work especially in a controlled environment. Sometimes you don't want a long 3 dimensional tone, you want something quick with no overtones. I am excited to try this in my little home studio set-up with some gated reverb... Not that concert toms only work for the Phil Collins sound.
