I used to not care whether a bridge on a Fender top loaded or strung through body. All sounded the same to me. Today I got an 09 Precision and restrung it top loaded with XL rounds. The E string had a rattle to it. Wasn't a bad rattle...just a little annoying. Restrung it thru-body and the rattle went away. I'm convinced...at least in this instance Discuss. Again.
