The "no luv" thing has always been about the tone for me, I've owned a total of 3 over the years but just couldn't ever come to grips with how they sounded.
I ran into Sekou Bunch recently, he's a great session/sideman player who is a Carvin endorser (we have the same tech) and told him my story. He advised me to try the new Sb4000 since I'm a Jazz guy and that it would change my mind.
Haven't gotten around to that yet.
Since that's his bass doesn't really surprise me. But I love my SB5000 so can't say I disagree with him.
