Hello,
I love this sound on a kick! Single ply heads on both sides and NO hole in the front head. What I have found useful in to take one regular felt strip, about 2 inches wide, and cut it length wise. I then use the one inch wide pieces under the heads. one per head. That way you get a bit more tone.
Also, using a ribbon mic on the kick. If you do this be sure to have the ribbon at a downward angle so you down blow it out.
I can send you a sample of this sound if you would like.
