One thing I do in that situation is place a strip of paper between the snares and bottom head. Quieter with less snap. The closer to the center of the head you slide the paper strip, the less snare response, so you can adjust the sound. I find the snare effect is the greatest contributor to volume, as can be tested by disengaging the snares, and finding the drum is no longer too loud. :)Mitch
That is a good idea. Thanks for passing it along!
