Capo Buzz/the bigger issue

[Lance Lafargue]

Thanks Mike.  I agree.  I do concert tuning and I'm often frazzled
trying to perfect the piano between performances, hearing "stuff" I
don't want, then I go out into the audience and the piano sounds great
with none of the bad stuff noticeable at all.  He does want to record
with this one.  I'll post the outcome.  Steinway approves of me
increasing the angle on the speaking side i.e. the Revenko-Jones italic
u shape.  I will look at the piano closely first, talk to the customer
at length, maybe try reversible fixes, and then proceed further
__carefully__.

Hi Lance,
     Sad this customer is depressed.  Many new piano owners question us
about what they hear to see if they should be worried. Often reassurance
is all they want, or validation the piano is a good one.  Even the best
contain compromises, minor annoying noises,  harsh qualities, relative
weak ranges / notes, whangs, twangs, pings etc.   Any one could become a
warranty issue.   
      I would fix/minimize/compromise using only reversible methods.  In
fact, I personally wouldn't alter the plate on any new piano if the
builder told me to.  (Too much liability and hassle).  Let the customer
decide how much tone they will sacrifice to reduce the noise,  but guide
them to a good decision.  (For a stage,  any noise that doesn't reach
the first row really isn't worth compromising tone for, but it's the
artists decision always)

narrow the bar on the speaking length side, given everything else I have
tried?  Is there some consensus, given the problems with the design?
And how do I determine if I have a > "> soft> ">  V-bar?  Voicing did
nothing permanent but continue to weaken the piano.  I plan to call
Steinway first before I do anything further.  This owner of a new B is
currently, officially, depressed  ;  )

the patent descriptions sufficiently well to know if they confirm or

movable cast front duplexes still seen on so many older S&S pianos.
