[CAUT] Humidity, Bridge caps, pitch drift

[Paul T Williams]

Good to know David!

I still may try out one of these retro-fitted-Nossaman pianos on one of 
our Steinways someday.. I'm really curious.

Fred:

I'll have to chime in here and say that our two pianos with a Nossaman 
epoxy laminated bridge cap really help tuning stability.  One of those is 
next to a D with a stock bridge and there is quite a difference in the 
pitch stability.

                 For me, anything is "a notion" until I've actually tried 
it myself 
<G>. Tantalizing to me until I get the chance. I'm sure it has a good 
effect. My question is how much of the total picture is the bridge 
cap, and how much is elsewhere.
