A little late to this party, but I did find this, from some forum or another

"...the Leo Quan Special Edition package of the chrome Badass III bridge. It has two (2) sets of bridges, which are interchangeable. It has the Grooved Saddles (the "Billy" saddles) and a set of the Full Saddles (the "Bob" saddles). The Grooved have more attack, and are ready to go right out of the package. The Full saddles are 'woodier/warmer', but must have custom grooves cut into them. It is recommended this be done by a professional who will take into account your strings, style, etc. "

"...two kinds of BA 3's currenting in production. one is known as "bob", which has flat saddles that need to be filed for your strings. the just recently came out with a BA 3 known as the "billy". now the billy has little grooves cut into the saddle so that filing down is not needed. if you dont believe me next time you see a Badass III bridge turn over one of the saddles. their should be a name under them, either billy or bob."
