I just had a Dampp Chaser installed today in my new Yamaha GC1 Grand piano. I heard such a difference in the tone after installation.

My grand sounded much more bright with a biting tone to it. Is this the piano's reaction to moisture and to the Dampp Chaser?

Is this a typical reaction found by anyone else.

I have never had that experience and I have Piano Saver systems on all three of my pianos. There is no possible way that it could possibly affect the tone in a few short hours. I have never experienced any tonal difference ever caused by a Dampp-Chaser. You mentioned that it is a new piano, Did the tech/installer do any voicing? Was this its first in home tuning?

Did you do some furniture re-aranging? New artwork hung, perhaps? Are drapes now open when they are usually closed?

I would look for other causes than the Dampp-Chaser.

I had parts of this Dampp Chaser installed in my 105 year old Everett upright without any problems and it worked great for about 8 years.

This was a year and a half year old Yamaha GC1 used by the Von Maur stores so it was fully ready to be played. I had it tuned last week for the first time after it was moved to my house. I have had it for almost a month now.

The tuning probably drifted because of the humidity change. Did your tech schedule a follow-up tuning appointment?

Yes, I am getting a follow-up tune up. I think the tuning did drift because of the humidity change. Thanks for your comment.

May be you could crawl under and check to see if any of the 2 metal rods used is not vibrating or installed in torque (tensed) that could make it vibrate. (lightly tapping on them).
Or a dehumidifier rod, that would be just a vibration.

Never noticed such thing, acoustically the
re may be little incidence, but something is under the soundboard, partly deflects tone, could it be that your floor/room is very reverberant and that add a bit more ?

The eventual added moisture would need a few days before any change in tuning , plus we are in humid season I guess so if any change it would be the other way (and that will take also more than a few days)

Thanks Kamin,
I think waiting a few days is good advice. Any change like this will take the piano some time to adapt.

A dampp chaser installed in the summer will take the middle of the piano flat in pitch in relation to the treble, creating a greater amount of octave stretch in the treble. More treble stretch in a Yamaha will make the piano seem brighter. Tuning a piano will make it sound brighter as well.
