Yes,
When dust accumulates beneath the rubber keypads, which granted it will take some time, the electical conductivity will decrease to some degree. The same holds true with some types of switches. The worst problem, though, is when dust accumulates on the leaflet contacts of 1/4-inch jacks and combines with cigarette smoke and humidity. Then it turns into a black, gooey mess than really causes problems. I had to deal with this with one of my fan-cooled amps. The air was drawn not only through the air intakes, but was also being pulled through the unused jack openings. At the end of three months of performing in a smoke-filled bar room, many of the channels would no longer function unless you wiggled the jack a bit after it was inserted. The amp head was still under warranty and sent back for repairs. The tech called and said the entire interior of the amp was covered with dust and goey cigarette tars. Covering you equipment just makes good sense--something like parking your car in a garrage.

Though I don't currently use a dust cover on my Tyros, I like Donny's 'Cover Your Ax' suggestion (vs the Yamaha brand one) because it includes elastic to secure it (right?). I suspect Yamaha's cover doesn't include elastic, does it? On the other hand, the Yamaha covers are customed sized to fit specific Yamaha keyboard models. Ok, if I go with a 'Cover Your Ax', exactly which size (small, medium, long slim, large, extra large, extra slim) BEST fits the Tyros dimensions (44.88" x 16.85" x 5.40")? Scott

Originally posted by rattley: Hello...........On Dnj's link.......what size cover would fit a PSR3000? Thanks. -charley I have checked this, and you can find the different sizes through THIS LINK The sizes of the PSR3000 are (according to the manual) in inches app: 39 x 16 x 7That would mean that the medium size is just too small (39-41.5 in. long x 12-15 in. wide) and the large one is too big ( 42-50 in. long x 15-20 in. wide) Fran's Keywear Covers look good too. For PSR keyboards (61 keys) it should be the Medium size, but it doesn't say how far it will stretch. Fran, which one do you have for your VA-7? (dimensions VA-7 are appr. 47 x 16 x 8) For both types of covers: are they anti-static? ------------------ drdalet
