No, just the saddle.. the small part of the bridge that directly touches the string.

Knife edge saddles look like http://www.k-t-s.com/contents/bridge/fig/PR-01dwg.jpg
Notice its higher on one side than the other. I represented this with the "text art" /l or l\

If you remove the saddle and reverse it it will gain you just another 3/16th or so of adjustment.

Notice in the following link (insert pic didn't work) tune-o-matic has some saddles face one direction, and others are reversed.

also I tried copying the link to an address bar... it timed out.
