I need a fairly focused, yet full bass drum sound that is close-mic'd with an AKG D112. I have used a "Dead Ringer" in the past on the batter head with good result. Most recently, I decided to stop in the handy home improvement center & picked up some weather stripping with self-adhesive backing. I snagged 10 feet of 3/4 inch foam & stuck it to the perimeter of the inside of the batter head as to touch the shell of the drum. I did a similar thing with the front head, only about 2 inches in from the edge of the head (I did this without the head being mounted to the drum--the res. head also has a 6" hole in it). With both heads, the foam makes a complete circle.
VOILA! Great kick drum sound with no "laundry" lying inside the drum, and all for about $3.00 !!!
