It's a good looking bass and I'm sure it plays as good as it looks.
It is a new model. Designed in conjunction with noted bassist Sekou Bunch. It has a Fender compatible 20 fret neck as opposed to their other bolt neck bass the B40 which has a 22 fret neck, and the neck-through basses which have 24 frets.
I haven't played an SB4000 yet but I love the neck on my B4.
