As an Alembic Spyder owner, I think Warwick is trying to copy Alembic, but not making the mark. I don't think Warwick is claiming this as a "John Entwistle" bass, but if you look at how they're made, they're clearly trying to copy the Alembic Spyder. It might be a nice instrument, I don't know. I guess I'd have to play one to find out.
And they're not cheap. I saw one on Bass Northwest's site for about $5K. For that kind of scratch I'd go to the source - Alembic, and get a better instrument, IMHO. I paid $5600 for my Spyder, new, with case. I don't think I'd pay that much for a Warwick.
