As another guy who has a fever, the only for which is more Warwick... I would also recommend wait. I have played the rockbasses and while they are not bad instruments, they lack 75% of what makes a warwick a warwick IMO. What are probably the biggest warwick tone factors? Wenge/ bubinga and the bell metal frets + brass nut. The things that the rockbass leaves out. Plus there are always used warwicks on here for decent prices. As soon as I sell my bongo i will be buying one of them.
