I recently bought a 1962 Ludwig Jazz Combo snare (3-1/2"x13" piccolo). All of the hardware is chrome, except the round tone-control knob, which is nickel. As the tone control also has a bunch of extra washers stuck in to push the knob out far enough to clear the hoop and in fact still doesn't actually work, I assume that it's an incorrect replacement. Baseball-bat controls don't fit either, as the holes in the shell are both pretty small and won't accommodate the thick main post of the baseball bat. What seems to be needed is a round-knob tone control that isn't as tall as regular ones, since the holes in the drum shell are placed about 1" and 1-1/2" from the batter edge, rather than the usual 1-1/2" and 2".

Does anyone know what the correct tone control is for this drum and how to go about finding one? Thanks much.
