Jeff makes a great point here - actually listen to your kick drum and see if it's the sound you want. Try to get someone to play it for you and walk around and listen in different locations to see how it changes. Obviously when you get your head close it's going to have to be played softly, but this is still a valuable experience. If it doesn't sound right when you put your ear where the mic is going to go, don't expect it to magically sound right once you hit record.

I appreciate the advice. I am using four mics, 2 OH, snare and BD.
I've had my friend play the drums and I think the BD sound is working.  The beater head has a muffler ring

What's it sound like in front of the hole? Inside? Well I've tried all sorts of combos and I guess with my particular kit I have just not found the magic mix of tune, muffle and placement. I'll keep trying. I'm just shocked it doesn't sound better than it does pre-processing, based upon what I am hearing and seeing.

Because bass-drums are innate 'gross imperfections', they suffer: 'dirty' harmonics, sonically-escewed noises, varying distortions in various rooms, resonating, long-waved-requiring-high-ceilings, etc.)

... I'd use a cheap mic connected to a low latency fx-box to approximate the bass-sound sound you want: You'd tweak the box's EQ, comp, harmonics, pro-bass-drum- emulations, verbs, etc.  (I'm assuming Railroad Bazaar techs can help here ... I dunno)

I'd (perhaps unprofessionally) prefer this mic method for recording ... and for live performances ... especially for listeners out-doors or in a large theater.

IMHO: Your/my listeners expect a 'good' bass-drum sound in the Western world ... regardless of how its 'recorded'.

I have a 20" Pearl that has an Evans EQ2 batter head and the stock Pearl resonant head with no hole. I use the Shure Beta 52 and a Shure SM57. Both are pretty much 3" from the front head about 2-3" to the right of where the beater would hit (obviously extrapolating here as the beater would not be hitting the resonant head). I have a pair of overheads as well. The B 52 gets excellent low end sound. The Sm57 gets mid and higher range freq and a good crack. The overheads get good crack as well. Record a few drum tracks and then mix the sound volumes to get the sound you're looking for. As far as EQ, I boost about 1k on the SM57 kick mic and low pass the B 52 while boosting at about 650 hz. In my mix, the 57 and 52 are quite low - the overhead gets a great sound and I use the 57 and 52 to fill in. Maybe you are trying to fill in using your kick mics and they are overpowering your mix. My bass drum sounds great to my ears. No muffling at all (other than what the EQ2 head provides). As stated earlier, you need the kick drum to sound 'right' to your ears first. Play with the positioning of the kick mics until you hear what you like. There is no magic bullet. I set my mic position and happen to like what I got, so I keep it there. I remember it's position in case I move my drumset. The key is that the kick drum has to sound "right" when you listen to it by ear. Also remember that distance can increase your low frequency response. So try moving a mic farther back (noting that you will get bleed from the other parts of the drumset). Try porting your resonant head and placing a mic inside the drum. Point the mic at where the beater strikes the batter head or aim it towards the shell. Experiment. When I was using a mic inside the drum via a front head hole, I aimed the mic at the beater from inside, about 6" inside the drum (as measured from the front head to the front of the mic). Placing the mic directly in front of the front head hole might not give you the sound you want because of the amount of air rushing out of that hole when you hit the drum. My suggestion would be to move the mic farther inside or farther away from the actual hole. Or do what I do - no hole. Remember that you can keep fiddling with your sound endlessly - or just get what sounds good and play drums. I honestly just get a good sound, make sure there's no strange buzzes/rattles, check for phasing, and play the hell out of my drums. You can hear a test drum sound I uploaded to SoundCloud, Search for deralds you should find it. Its just an example of a drum sound but you can see if it's something you like.
