I know that George has discontinued offering the Studio models but I'd be willing to bet that he did build quite a few when it was a part of his regular lineup. There always seems to be a few used BN5's floating around but never any Studio models. I'm going to assume that those that have them aren't giving them up. Brad Johnson swears by his Studio and isn't giving that bass up for nothin', right Brad? Who else around here has an F Studio? I'd love to put a Studio up against my dearly beloved BN5.
