Ok, this is a dumb question, but I'm kind of confused. Can someone tell me the difference between a Bigsby B7, a Bigsby B70, and a Bigsby B700? Is the B7 a true Bigsby and the others Bigsby licensed vibratos? Are the licensed versions as good as the real thing?

The American is sand cast, both imports are die cast. Sand casting requires making a unique negative mold out of sand to pour the aluminum into for each one. Die cast uses the same reusable die mold over and over again.

 

The American B* series uses pin bearings on the roller. They look something like this...

The import B*0 series uses nylon bushings on the roller...

Also the some screw locations are different between two the American and import models.

 

I really don't know much about the B700, I think the B*00 series was originally only available as low cost OEM parts to guitar manufacturers.
