I used coated heads on the top and bottom of my set when I would crank it up into jazz ranges because I found that when I had clear bottom heads I would get a slightly sharper more pingy sound than if I had a coated / clear and any warmth is welcome at those high, high notes.When I first started playing in the 60s everyone had white heads on the bottom of their toms. Now it seems most everyone uses clear. I'm considering going back to the white because I just like the look. Never really thought about it until now, but that's going to change the sound since white are thicker ply. Right? So what can I expect from the sound? Less resonance and more thump? The toms will sound "dead"? Any thoughts on this or am I just bored?
I never cared for it at medium or low ranges though.
Here's a whole video on coated resonant heads:
