<div>Hi Ron,</div> <div>No I studied this and discovered a yawing effect especially just above the break in verticals, similar to the effect you get when trying to raise pitch on the old Yamaha electric grands w/2 string unisons that used the Ceramic pickup as a bridge. Nasty little pians to raise pitch on. I actually had center strings that I set at pitch with several hard blows, pull sharp after raising the corresponding outer string and found I had to find a balance point in order to get both at pitch.  </div> <div>On 8/10/07, Ron Nossaman <<a href="mailto:rnossaman@cox.net">rnossaman@cox.net</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> > One more nugget of info I have been tuning for a Kawai dealer for over > 20 years, about a 15 or so years ago Kawai began getting complaints > about string tarnishing, they'd turn black or dark rather quickly.

Yamahas do this too. One good whack after it's pulled up will do it, and the string will drop a couple of beats. It's not happening at the hitch, because you can quietly pull up both sides of a shared hitch, and when you whack it, both sides drop in pitch. I think it's the bridge. It happens in the capo sections, where speaking lengths are getting short. I've run into this often enough following "soft" tuners who swear you can tune quietly with good stability with the right hammer technique. I've followed them as little as a week after their tuning, because it needed it.
