I have a Vintage 4. Based on pics I've seen, I'd say they were all done by computer as well. The relic jobs are identical. The only thing I found strange was they applied the poly over all the wear spots. Does not matter to me. These are great basses.
I'm a poly fan, so I kind of like the compromise of getting a relic look, but having the durability of poly. And as far as computer/automated patterns for the relic job? meh, i couldn't care less.
I am very pleased with my current stable of basses, but I have to admit, I'm gassing for a vintage 4. I hardly ever see them for sale. I hope you enjoy yours.
