Well, i just got this thing from a TB member a little while back, and i used it a week or two and saw the bridge cover screws and thought "I think i have an extra cover and some screws!" So i screwed in my cover, it looked great. I started playing and after about an hour i touched the cover and it was warm. Weird. So i felt around and the screw closest to the input jack was HOT. Like hot, not warm. So i took the cover off, and played it again and now its so noisy. If i am not touching the strings its humming. If i touch the screws holding on the pickups when i rest my thumbs it buzzes. What did I do, and how do i FIX THIS?
