Hi David, Nothing will work perfectly--but install a dampp-chaser with bottom cover and string cover on the least stable of the pianos and let us know how much better it gets? For a six foot I'd recommend a 50 watt belly bar, and a 38 watt tail bar, bottom cover and string cover. At 01:30 PM 12/24/2008 -0800, you wrote: I maintain 9 pianos at the SF Ballet. These studios have wide fluctuations of temp and humidity. When dancers are in studio the heat goes way up...sweating bodies...at night heat goes down...or off...would a damp-chaser help in this situation? It seems to me it wouldn't be able to react that quickly...? Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.P.T.
