Voicing on the capo side of the hammer only will reduce buzzing with =
little loss of power, maybe enough to avoid other fixes. (This was =
taught by Fred Drasche and is also in the Renner voicing instructions).

If that doesn't work, a thin strip of bushing cloth woven in the front =
duplex can be "voiced" by sliding closer to or further from the capo =
bar.=20

Just for curiosity you might try a slight change of strike point.=20

  I have always struggled with the capo buzz in many pianos. Young =
Chang/Prambergers I've never succeeded with, Steinways, I usually can do =
it.   I have discussed this many times with many techs.  I am exhausted =
after a 14 hour day with three B's one of which is still giving me fits. =
 It is a new Steinway B, prepped by a large reputable dealer.  The piano =
was/is nice.  But it was a little bright after some play and I went in, =
pitch raised it, stopped sympathetic aliquot ringing, leveled strings =
with my Mother Goose leveling tool, fit hammers to strings, worked on =
damper bleeding, etc.  There were several hammers, especially the first =
C at the V bar that had a buzzing quality.  I sugar coated/voiced, 3/8" =
needled the shoulders, evened everything out, got it acceptable, and the =
buzzing returned, a bit.  Enough to bug the customer. =20

  After more sugar coating (shallow needling at crown) and more 3/8" =
inch needles just off of the string marks (both straight down and in at =
an angle), I am at the point where I am killing the bell quality and =
volume to extinguish the metallic buzzes.  I believe these hammers were =
hardened with lacquer, not key top solution.  Tapping strings onto =
bridges, done, seating strings at every termination point, done.  This =
exists to some extent throughout the V bar area.  This is the buzzing =
that goes away when you put your finger on the front duplex section.  =
Just hoping I may hear something new (hoping not to hear a buzz).  I =
appreciate any new suggestions, I am so worn out!
