Hello, Isaac, I would say yes, this is a prime candidate for a large DamppChaser installation, if you think it will be kept plugged in and if you can get to the piano NOW for the installation, plus an extra one in the action box to free up the action. It will take two to four weeks for the piano to stablize to the new humidity. The extra one in the action box should be removed when you tune it next. You will most likely need to install three hot long ones under the soundboard and one under the keybed behind the lyre. One control unit for the entire system. I would also treat the hammer bushings with Protek CLP if you can get it. Newton nhunt@jagat.com
