You may think I'm nuts but here's what I did.
I found out a long time ago that (to my ear) the bass drum sounds best (muffled) when the muffling is held against the inside of the batter head with a good amount of pressure. So I went about devising a homemade muffling system that would do that. Basically, what I did was create an internal muffler for my bass drum that is just like the mufflers found on vintage snare drums, only bigger.
Yup, I took a perfectly fine DW bass drum and drilled 4 holes in the bottom and mounted a 3" round, female threaded, flange base to the bottom, with a homemade leather gasket between the metal flange base and the wood shell. Then I screwed a 3/4" x 6" pipe nipple into the flange base nice and tight, clamped a dogbone on the pipe, put a cymbal boom arm in the dogbone, and somehow attached a 8" x 5" piece of t-shirt and duct tape wrapped plywood onto the threads of the boom arm. The cotton wrapped plywood does the muffling and the boom arm provides the pressure. I vary the pressure from nothing to maximum by how far the boom is extended through the porthole in the reso head.
I love the sound, and I'm betting that not many drummers have pressure muffling in their bass drum.
I also clamped a 2nd dogbone on the pipe inside the bd to hold a mic clip, which holds my audix d6 mic all the time, I never take it out. One less mic stand, one less mic to set up and put away. I just plug in my bass drum mic through the reso hole. I'm just glad I don't play clear acrylics because the mod aint too pretty ha ha.
I did this originally to my home set, Pearls, and was so pleased with the sound, I did it to my DW's.
