Dampp-chaser experience

[Bec and John Silva]

Hi,

I have been meaning for while to write the list, mainly for any  
sceptics, about my experience with a Dampp-Chaser system.

I had installed one in a Boston GP193, used in a church which keeps  
the heat very low (55ºF) during the winter and doesn't turn on the  
air-conditioning in the summer - both come on as normal for Sundays  
and special events. The unisons would usually be quite out of tune  
within a month's time.

After installing the dampp-chaser, for about 6 months it made no  
difference. Then, what seemed like all of the sudden, it started  
staying in tune and has for the past year or so. I touched up the  
unisons about a month ago and just heard the piano last night, and I  
would have thought I had touched it up a few days ago.

I am bewildered at how much this piano is staying in tune, I was a  
big sceptic.
