Well... it seems that the new Vintage Pros are readily available (
finally!). That's where my money would go, if I were in yer shoes. First... because it's gorgeous, neck-thru, & 6 hunnerd bux!

Second... because, though it was obviously inspired by the early Thunderbirds... it also represents the present, and most likely the future of the 'bird. It's the
perfect time for you to buy that
specific bass. You have no biases for it or against it. It doesn't matter to you how it compares to its predecessors. It only matters if you like it or not!
