i recieved the decks and mixer this past wednesday. these things are pretty decent. i tested them out and have given them a workout a few times. but last night i noticed something that makes me feel that something might go wrong with a deck in the long run. on the "key lock" and "pitch" buttons, the light is real dimm and all other buttons are fine. the other deck is nice and bright on all buttons. i dont wanna send it back quite yet but i will keep playin on it unless a problem arrises. any suggestions?
