Thank you for the suggestion to stretch the treble more Mike! The UST-9's are gorgeous from every point of view. The fact that they were quite a bit out of tune is not surprising when you consider 48 hours in an unheated truck in the snow!

Fortunately the college where I am tuning has purchased these pianos, so they won't disappear just when we get them settled in. However, my question is this; in a practice room in a small college, how long, or how many tunings do you think it will take for the school's new Kawai UST-9's to stabilize in tuning? The pianos were delivered directly to the college from the warehouse and uncrated there. Before that they spent two days in the truck. It was snowing outside. They have Dampp Chaser heating rods and HD humidistats installed, but my data logger, which was in their new Boesendorfer between December 4 and February 4, showed nothing but too dry. Every time I have tuned in the practice rooms, my humidity gauge reads 36-38% RH. I do expect the humidity to go up to around 60% in the spring. Each piano has received one pitch adjustment--usually pitch raises, but two of them took lowering--and one tuning since the beginning of February when they were delivered. Already I want to tune a couple of them again, but this is not in the budget or mindset of either the store that sent me out or the college who now owns the pianos. They all think the tunings should be stable already. Experienced opinions gratefully received! Diane Hofstetter Hi Diane, My experience is primarily with UST-7's & 8's having contracted to a Kawai dealer for over 20 years. My info is that the UST-9 isn't appreciably different except for the action materials. I've found that they stabilize with time and 3 or 4 tunings, they can't be "hurried" but instead need some time in between to acclimate. Be aware that these were probably assembled in China and my sources tell me that they have been coming through in good regulation, no report on tuning. In the good old days when they were made in Japan they used to arrive not only in tune but a little sharp, sealed in plastic wrap of course. But I digress.......... My suggestion would be to put a little extra stretch as you work your way up, it will help it to acclimate a little faster. Mike -- I intend to live forever. So far, so good.
