It isn't? I have to disagree, and to prove my point, here's the description from
Warwick's site:
"This archtop set neck bass with double cutaway is dedicated to a great Jazz musician, the Swede Jonas Hellborg, who, like almost no one else, masterfully combines Eastern music traditions with Western. The construction of this bass is distinguished by a hollow body, the arched back and top, as well as the notch are made of AAA Flamed Maple. The front and back side of the body is bound with white/black celluloid . A Tigerstripe Ebony fingerboard is glued to the AA Flamed Maple neck. The double cutaway offers easy playing in the upper neck positions. The passive MEC Soapbar singlecoil humcancelling pickup is controlled by a single volume pot. At the trussrod cover is the signature of Jonas Hellborg, on the rear side of the headstock H.P. Wilfer has signed."
Even
Link Removed, which is actually Dana B. Goods' site, not Warwick's own, clearly states that the Hellborg signature is an archtop. So, it
is hollow alright (thank godess!). I really want to try one, though I can't imagine ever buying one.
