The brass plates tend to pinch the reed at the point of attachment, especially if they are over tightened.

Just looking at the pics the brass plates do seem to be distorted , they are very thin and distort very easily.
 
Try to straighten the holding plates, and do not over tighten the screws, they are really only a nip up, .7ft lbs.

Use blue Loctite, you do not want them suckers falling out.
