Tuning a concert piano with humidity control

[Don]

Hi Jerry,


I'd go with the single tank and bottom cover. I have done bottom covers
with tanks that hang beneath the beams. It is still esthetically better
looking to have the bottom cover than to see two ugly tanks below the piano.

I'd still arrange for any system with or without bottom cover to be plugged
in, or do the ups solution. 

My "ultimate" humidity control system would include an Edward's String
Cover too.

My experience with floor length covers is that they don't help much. I have
one performance instrument where the piano has a floor length cover. After
a bottom cover was retrofitted there was a significant improvement in
stability, both at the tenor break and unisons.

I would try to tune as close to the concert as possible. In that ideal
world the piano would be in position 8 hours before the tuning in
performance conditions.
