I used to have a vintage Rogers Dynasonic that had an internal tone control. I have read a lot that a lot of guys took the internal control out of drums, citing "rattle" problems. So, my question is this: what was it, exactly, that rattled? Was it the screw that went through the shell that secured the controller to the shell that came loose? What was it that rattled? Did it rattle all the time, or just when on or off? iI think that there is a place for these, but only if the problems can be permanently fixed, so I am willing to "make a better mousetrap." I would revamp the felt, which is rather hard, and adds too much pressure too fast, limiting the dampening window. But first, the rattle issue, and I need direct feedback on the actual problem from those who had experience with them. Thanks!
