string "noises"

[Allen Wright]

I tried pitchlocks to no avail today. Also pulled the action towards  
me a bit with no apparent change. Voicing helps only to the extent  
that if any of these notes are louder in volume, naturally when  
they're voiced down the partial shimmer is down as well - but still  
noticeably different from other notes outside this area.

Several other new B's and (to a lesser extent) some D's I've checked  
have the same sound in this area.

Thanks for all your suggestions; if I find anything that works, I'll  
certainly pass it on.
