I've heard the Bass Pod pro is intended more for studio use. Does anyone use it at gigs? If so do you use it on its own as a di into the pa system or just as a tone-shaping pre amp to your miked rig. Also with the big bells and whistles rack mountable version would this become the amp that drives your cabinets or is it still just a pre-amp? How cheesy (or not) are the built-in effects? As you can tell from these questions I've always spent my money on basses rather than amps so my knowledge of same is pretty basic. Any advice based on experience appreciated.
