Gaff tape (NOT duct tape!) or Moongel....

The only thing I use for dampening is an emad batter head on my bass drum.

I WILL use duct tape sometimes (hence my username LoLoLoLo)

personally I prefer using head choice as the means for dampening. That said I do use Emad for my bass drum. But I prefer a more open sound. I don't care for a very dry sound. When I play the drums are usually unmic'd

For snares if I use anything at all (usually don't) I use the good ole muffler, usually just the lightest touch to cut the highest overtones. Bass I use an Acquarian Superkick and generally a rolled up pair of chef pants for a hair of extra muffling. I don't muffle my toms at all

I have in the past (with a 18x20 kick that I could never get to sound good) used a bag of rice inside my bass drum. I took a pillowcase, dumped in a healthy amount of dry rice (don't be shy, fill it 1/3 to 1/2 up), then tied a knot in the open end. You can press it as little or as much as you want against one or both heads, and it mostly keeps it's shape without having to adjust often. This works best with a port in the reso head, so that you can reach in. You can even put the bag in and take it out through a port. I sometimes found that putting it in but not having it touch the heads at all worked well too. You can adjust the amount of dampening by adding or subtracting rice.

This does 2 things: adds some mass to the drum and dampens the overtones of the shell, and provides something to dampen the overtones of the heads. This is mostly a solution for a bass drum that is too resonant due to being too deep. I think it would be too much muffling for a 14" deep drum, but that's just personal taste.

Factory installed muffler (snare only), lightly cranked.

Felt strip on BD (batter side).

Nothing i let m sing

I am old school in some ways. I like the felt strip in snares or toms and I use an Evans EQ muffler pad in bass drums, provides a real low end thump and its adjustable. Alot depends on the size of the room. In a smaller room everything rings. In a larger room or outdoors you lose most or all of the ringing. If the sound can't get out... it comes right back.
