I took the front head off of my kick drum to take out the pillow i had in there and i put a piece of foam 4inches thick by 8 inches wide and long enough to go around the whole inside of the drum..I think the drum sounds better with no head put back on ... way punchier!!! anyone else out there like it better with no head on???? It will also make it easier to record as i can get the mic right inside ..
