Whole room humidity control better than Dampp Chaser. ( Right?)

>>A DC system really can't be effective in a grand without a string-cover. 

 

I have years of anecdotal evidence on scores of installations that say
otherwise. Perhaps a string cover increases their effectiveness, but on many
of my installations I don't know how. I'm talking about pianos that had +/-
25 cent seasonal variation that went to +/- 2.

A DC system really can't be effective in a grand without a string-cover.
Even then it doesn't really help the front key-pins.  An undercover is
recommended if the place has forced air heating/conditioning.

My wife's concert grand wouldn't stabilize until I made both additions
above.
