Westbury was just the US importer's name. Just a brand name slapped on various imports. Some of them may have been bad, that doesn't make all of them bad.
crap. not everything made in that factory was good, imo.
I don't know about this particular bass, but you're right. That factory made different grades of guitars at different price and quality levels. Whatever the importer called for. Yet somehow there has gotten to be a cult following who think that everything coming out of there was great. I haven't seen anything personally that I'd drop $600 on.
