I too have the same issue since converting over to 682 mesh. Only on the 10" Snare pad. All of the tom pads are perfect. I tried changing the foam cone to a firmer type to see if it was a case of not enough transfer of vibration. Unfortunately that hasn't fixed the issue. I plugged a smaller pad into the same channel and its loud so that rules that its definitely pad related. Might have spend a bit of coin and buy another pad.
