I was just wondering what the sound characteristics are for Remo's CS Black Dot heads. I am looking into trying them as batter heads on my toms and I would like some sound description as well as some opinions on these heads as tom heads.

They will definatly give you that classic booming "Thundering Rock" sound.
They were staples in the 80's for alot of cats.
I have deepshell racks and when I put the BlackDots on there they just sound "meaty, beaty, big and bouncy"!
The kind of sound you feel in the 3rd row.
The smaller rack toms ( 10 and under ) they tend to give a tad more ringy-ness (?)  than I care for, but a piece of gaffers tape ( Duct tape ) on there settles it down rather quick. The bigger racks (15-18) tend to get a little boomy so I use a dampening ring that is cut from an old head to control that when I need to.
Your choice of reso heads will make a diffrence on how they sound as well.
I use the Evans clear hydraulic for the classic sounds, but switch to standard remo 1 ply reso for most middle of the road stuff.

They will definatly take a beating where the dot is and will last for a while, but the head outside the dot gets marked up pretty quickly if you miss the sweet spot. Also once there is a big divot in there..just go get another head...they will not sound right and you will want to slash your wrists trying to get a good sound out of a divotted head.
YMMV

What are CS's like for bass drum batters? Especially in situations where you bury the beater and rest it there.

thanks very much! that's my bop size Zickos kit in that pic. i have a second Zickos kit that is bigger shell sizes, and it's the one with the CS heads on the toms.
