Found out what was making my "new" piano (had to replace the one I lost in the fire - got this one for $50!!) clank every time you hit a key. I was starting to not like it and wishing I had shopped around and not been so hasty in getting it cuz it was so cheap. It's fixed now, though, and sounds fine!! Except it's part of the lid that moves back and forth over the keys. Kind of just have to take the whole lid off to play it and then put it back on when you're done, but I can deal with that.
