The dry climates I'm talking about, such as the high plains or Rocky Mountains, spend most of the year at a far lower humidity than 40%, where the Dampp-chasers kick in. And asking a rod or a couple of rods with 25 or 50 watts of heat to overcome a muggy Eastern or Southern summer is unreasonable, which is why the full Dampp-chaser system has to add water in the winter, instead of keeping a piano as dry as the Gobi desert or a New England living room in December. Besides, when we're talking about verdigris, it is usually in grand pianos. The Dampp-chasers are under the soundboard, removed from the action cavity. If one is put in the action cavity, it risks hurting the pinblock, and for that reason is usually a lower wattage. >>From: Susan Kline <sckline@home.com> > >>My theory: verdigris forms much more readily in damp climates, but doesn't >>recur nearly as badly in dry ones.
