I tried one. It is very, very, very close to my SG Reissue Bass. The differences:
The lacquering is a bit thicker, de body is also a bit deeper than a Gibson, so it feels a bit heavier/more solid. A bit. The contours are a bit different and the lower cuaway is 1 fret deeper. So less symmetrical. Also the pickguard is a bit different, but most thinks were only clear when I tried one, next to my SG Bass. And as said, the sound is very close.
I would try to find a second hand matte lacquered SG Bass, but if difficult, this is a very good bass!!!
