I have one of these, the older black and gray one from 2009/10 or so. And I have used it for recording quite often. Who out there in Bass World has used one of these as their "MAIN LIVE RIG PRE-AMP" and run it into a Power Amp of some sort as opposed to using a Bass Head? And if so how are your results in configuring your rig this way using this pre-amp? Beings I have this one I have thought about using it in this way.
