I have two, and they're complete opposite of each other, so I don't know how one could generalize "Warwicks."
My Corvette $$, I absolutely love. It's a heavier bass, with a thick neck. High output, with a versatile sound, from being muddy to very trebly. But very punchy mids and highs that stick out in the mix.
My Fortress One, is very light, really thin neck with very low action. It's a gorgeous bass, passive, and pushes very strong lows through the mix, but with the EQ on flat, it's mids kind of dissapear compared to the Corvette.
Point is, they're two Warwicks that feel, play, and sound completely different. The Corvette is my main player, and I absolutely love the thing. Picked it up used for under a grand used(can't justify spending what they cost new), and can't see myself getting rid of it, or switching my main bass to another.
