'improved operations to give us a more consistent instrument from bass to bass.'
I don't know if operations were 'improved' as much as the change being a necessity for Warwick to compete in the market against companies like Fender, Gibson, Music Man, Ibanez, etc. I'm not knocking these companies(I love Music Man basses), but they mass produce instruments to meet demand. If Warwick wanted to be more then just a boutique brand and run with the big dogs so to speak, they had to switch production methods, and in some cases materials used, to keep up and keep their instruments/prices competitive. You don't see J basses or Sting Rays varying slightly from bass to bass, so things had to become more mechanical to do away with the slight differences and to speed up production, or modernize it.
And while they do produce 'a more consistent instrument from bass to bass', I think this has replaced the charm of the vintage Warwicks. Warwick, as a company, was only about 6 - 7 years old when I first fell in love with their basses(Thanks Jack Bruce :wink: ). I own two 'vintage' Thumbs as a result, both 1990 models, and they have slight, but noticeable, differences in shape, finish, etc. and I love that about them.
To me, that makes them feel more like custom basses even thought neither one is. It gives them a more 'boutique brand' type of feel. Which back then I think that is how many people thought of Warwick. Like Ken Smith, Fodera, Pre-Gibson Tobias, etc.
I'm not knocking newer Warwicks per se, I just think they seem a little 'sterile' compared to the vintage ones. Plus I don't like the thicker necks and some of the materials that are used now as opposed to the old ones
