I and some others have done quite a bit of research on Dampp Chaser, and we didn't find the same results as you did. WE didn't get bad information, because the only imformation we got was right "from the horses mouth" so to speak. The main thing that we found ( I won't bore ALL of you with ALL of it) was that humidity travels about as fast as cigarette smoke: between 20 and 25 feet per second. With that small amount of water (in that small tub in the piano) how can Dampp Chaser hope to supply enough moisture (especially considering that it is rapidly moving away from the piano to equalize throughout the house) to keep that piano at 40% humidity? Just a thought, any feed back would be much appreciated.
