Obnoxious Note (was Re: S&S capo)

Hi Roger & List,

   Since you chimed in on this, let me ask a question. This isn't the same
thing exactly, as Chris has, but I also have a new 'D' where E-2 (1st bass
string below the break) is giving me fits trying to get the tone in line
with the other notes around it. I've been using steaming and needles and
have improved it quite a bit, but it still sticks out some. All the other
notes have responded nicely to steaming. I'm almost to the point of
slightly hardning the hammers right above the tenor break to even it out
some, although I don't really want to.
   The hammer doesn't seem to be over-doped. The needles go in easily.
However,the sides of the hammer do seem to have a crusty, hard feel. The
dedication concert for this piano is tomorrow night and I'm trying to
finish up on it today. Any "miracle" ideas? Thanks.

Avery
