THUD

[harvey]

John, please report back if any of these suggestions work in your 
situation. I'm saving all replies on this as a double-check list, because 
I'm having (what I believe to be) the same phenomenon on a one year old 
'B'. In my case, the complaint is that those same notes don't "sound like" 
the others on hard blows. However, like Horace implied, I have eliminated 
voicing as a possibility.
In exploring other areas, when I rap on the plate, it generates what I 
consider excessive plate noise of the sub-sonic drone kind. Then, I'm from 
the old school who feels that plates should be acoustically inert! Besides, 
if it's a matter of "self-contained" plate resonance, I don't know how to 
fix that. I have noticed the "tuned" phenomenon more with V-formed plates 
than traditional methods, regardless of manufacturer.
