If you intend to buy a Bigsby B7 expecting it to be made in the USA and sand-casted, it isn't the case anymore since it is now owned by Fender. It was made in Korea.
We can see some cast iron marks on the bottom, that were not polished off, so I do perceive it as of lesser quality. The luthier who installed it said it looked very much like the counterfeits he encountered previously, but that's how the real deal looks like now...
That's the reason for the 3 stars as I think that's a shame, and it was not mentioned on the product page. But I don't think it impacts the playability in any way
