FWIW, I bought several brand new Warwicks (two Pros and three Rockbasses), and they were always perfectly set up, and ready to play. I only play flats, so I got rid of the rounds they came with, and I have slightly idiosyncratic tastes about action and saddle height, so I re-did the setup, but that wasn't because they were unplayable to start with.
I bought them from Thomann, but as far as I know, they don't even open the boxes, let alone set the basses up; they simply sell them on as they come from Warwick.
