Unstable piano

[Ron Nossaman]

>A  Kimball, studio upright, from the 70 or 80's I suppose.

Of all the pianos I tuned through the 80s and 90s, The verticals that went 
out of tune first, and farthest were the Kimballs. I don't see many of them 
now, for some reason, but those I do service still go out of tune fast and far.
