Re: What else have you guys used besides Moongel?
Moongels are expensive and they move around. If you hit one them, it's usually ruined. Most drum companies have stopped offering internal mufflers. Ludwig drums can still be ordered with the mufflers(Tone Control) as an option or you can buy just the muffler itself. The normal cost is around $20 each. The Ludwig mufflers tend to rattle a bit and can be annoying in the studio. I have fixed this problem with everything from duct tape to silicone gel.
