even more Dampp-Chaser thoughts

[Bec and John]

Hi,

It's been about 3 months since my first dampp-chaser installation. I 
did a tuning about 4-5 weeks after the installation. In addition, I did 
a big touch up of unisons and octaves mid-December.

Just recently I checked this piano (a Boston GP-193) and was surprised 
just how out the unisons were - I was expecting some noticeable 
improvement in the stability of the piano's tuning. Unfortunately I 
don't keep any kind of detailed notes about the state of the piano's 
tuning when I tune it, but from my memory (I've been tuning it for 
around 2 years, very regularly) it doesn't seem any more stable.

Any thoughts from those with much experience with dampp-chasers?

Thanks.
