I loved my Corvette Proline. Best slap tone I have ever heard. I would have kept it too, had it not been for the electronics. I learned that I was a passive bass guy after playing that beautiful bass. I was able to flip and make some money on it, but give me a passive Jazz everyday of the week.
I think Warwick is starting to get a bad rep from the less than stellar Rockbass products that have been coming out. I have heard some bad stories about necks pulling apart from the pocket because of flimsy wood. Have heard about DOA electronics. Have heard about neck warping. As long as Warwick keeps putting their name on those types of instruments, the more their reputation will sacrifice.
That said, bad products will only bring down the value of the nicer stuff. My MIG Wick was only $450. Poor sucker on craigslist is trying to get $400 for a Rockbass.... So, as I see it there are going to be some deals for you diehards. If you want to keep a company in the botique end of the spectrum, don't come out with a budget line. IMO, IME, YMMV.
