I currently play a Fender American Standard Jazz V and love the bass. I need a back up 5'er and want a Warwick. I will be buying used, but really know nothing of the different quality levels...i.e. Rockbass vs. Pro Series vs. German made. It seems sometimes you see an ad for a Rockbass Corvette, then another for a Corvette Standard and I can't tell if a Standard is Rockbass or just an older line of similar quality to the Rockbass.....it's confusing to me. I believe in paying for decent quality instruments. I'm a good enough player that I can make do with a cheaper instrument, but I can still feel the quality in my hands when it's there. Either that, or it's just in my head. So, out of the Corvette's, which series would be considered of similar quality to a U.S. Made Jazz?
