This is the first I've heard of this particular problem. Our humidity doesn't change quite as drastically as it does up north, so we just don't have as many Dampp-Chasers installed in pianos down here. >Has anyone found a way to deal with this >pitch drift problem while tuning?

Seems to me to be another good reason not to install the things in the first place, unless it's absolutely necessary. I wonder how many Dampp-Chasers are mistakenly installed to correct real problems such as tight key bushings or action centers, rather than correcting the problems themselves? Am I rambling? I think so... BTW, have any of you ever run across Dampp-Chasers installed *under* the pinblock in grands? Arrrrgh! Tom Seay School of Music The University of Texas at Austin t.seay@mail.utexas.edu
