It's a set neck. Funny, I just had a gig yesterday where I marvelled on stage about the huge sustain of my Bicentennial and Korina Birds, the bass player in the other band had a well enough sounding Cort Jazz Bass, but his sustain wasn't even close, my notes (over the same - his - Marshall solid state rig) just stood there and wouldn't go away. Only neck-thru does that.
Back to the topic: It's unfortunate that even Gibson as a once primarily short scale bass maker now seems to relegate short scale into the "for beginners, if you're hands are too small or if you are really a guitarist" corner. And isn't even the street price of this a little hefty for a beginner?
