Richard, I've just re-read Bill's reply, and agree with all that he has mentioned. With out the tarp, very little moisture will get to the action drawer. There was a big difference in stability having the instrument tarped when not in use. The tarp's cost us $600 CND to have custom made, far more expensive than the 5 part Damp chaser. We only have 25Watt dehumidifiers, and they work fine, our extreme high's are 50%. Roger Roger Jolly BaldwinYamaha Piano Centre Saskatoon and Regina Saskatchewan, Canada. 306-665-0213 Fax 652-0505
