I just posted in your other thread...I'll delete it.
"Paste"
My suggestion is the same one I give every time.
A piece of 1"
Polyfoam at the bottom of the shell.
Just a small width (spur screws to spur screws is
plenty).
It doesn't even have to touch either head.
Tape it down with a bit of packing tape (the kind with the strings in it) on the ends.
No muss, no fuss, it's clean, you don't see it, it doesn't move,
and that foam is really inexpensive.
The packing tape doesn't leave residue on the shell (if you want to move it), and it sticks well to foam (most tapes don't).
The foam in there to break up the sound bouncing around, and prevents any possibility of the basketball slap sound from happening--not for muffling. It doesn't inhibit and "resonance" from the drum like a blanket or whatever.
Leave the front head open, or place the foam lightly up against the head to stop any possible buzz/rumble, or to tighten up the sound if you want.
Or, use the tray thing and lose the benefit of the nice bearing edge & solid maple ring that the 3ply shell has....
The stock Ludwig head on the front has a pretty solid, nice sound on the bass drums I have it on. A remo white or Ebony has a touch lower pitch than a Ludwig--even when tensioned higher.
You have an EMad for muting the batter, and like I said, the foam is NOT in the shell for muffling.
It works wonders when the bass drum is mic'd for live or recording, and you can use a smaller 4" mic hole (which even large D112's fit into easily) using as much of a full front head as possible.
Even if someone has two P3 style heads, I'd recommend they use
something at the bottom of the drum.
Even one of those Evans EQ Pads work if you can get one/have one (the foam is cheaper), and it doesn't have to touch a head.
If your drum (as is) has been "easy" then of course no one is going to complain, but no one but you is going to "know" your drum, and what it's really capable of.
I just suggested not using the tray thing to get the most you can out of a drum that you paid big bucks for (and has a shell people seek out)--if you like a more wide open sound.
Your drum, do what you like, and what works for you.
I've just fooled around with bass drums A LOT and this method ALWAYS works great. Bass drums for me are like snares for other drummers (have 6)....
If you'd like, PM me, & I can email you a couple songs (with the 20x26) using this method and not even a pre-muffed batter head.
That's my 45 cents...
Good luck, have fun, and happy playing whatever you do.
