This is my Ex-Pearl Rythmn Traveller which I sold off.
I used those Remo Skin (with the Centre-Black-Dot from Swee Lee) on all Batters as can be seen......to make it look good (but dont use this on the snare - it doesn't sound good - look good only here).
Toms: -as all the Toms are (like Concert-toms) where bottom have no resonance head, I muff all the toms using those (Felts they used it on Chairs-legs) to stick onto the bottom right at the centre of the Black Dot (so you cant see it been muffled) and it will look great, and indeed sound good.
The Bass Drum: - exactly like what Mel had said - Stuff a Pillow not too big one against the Batter, tune it not too loose, not too tight (average) and you will get the right sound....
PS: - Do not stuff alot of pillow in the Bass Drum because it is very shallow and will sound very-dead if you do that, and worst volume of your Bass Drum can be very soft....
I did not cut a Mic-Hole at the Bass Drum, maybe it would sound better overall (I dont know here cause I didn't try this out)....
Just to share my personal experience here.
