I have an SB5000 and 4 and 5 string jazz basses. Both are great in a rock setting, and can cut through or sit back as needed. Live, I prefer an active bass because I feel like I have a little more note definition to counteract the soundman's tendency to think a bass only has bass frequencies. For that reason, I'd give the edge to the Carvin, and I generally use an outboard pre with a jazz bass. YMMV.
