The fever around 60's and 70's JB 's is exactly that. Fever. Once a fever is kicked off, some people get caught up in it. Now that it's real, in the sense that you can buy to invest, it's probably worth it, but paying that to just play is bordering on fever madness. Old Fenders were nothing special. As said, there wasn't much competition at the time. As always, YMMV
