The bass sampled here looks odd with the shape which is a bit like a Rick bass that's been flipped upside down and redrawn by a fashion designer, and the big mirror pickguard, but it's pretty much a typical Jazz bass underneath all that. The strings are a pretty typical set of roundwounds, too. So it's a pretty typical, bright-sounding bass, with the low range extended down to low A, and also more high range than usual thanks to its 24 frets.

The demo below uses no processing or effects whatsoever, though - it just shows what the raw samples sound like.
