The problem I am having with this whole thing is not the sound guy per se. The problem I have is the FOH system is not what I would have chosen as a stand alone bass rig to begin with.
I suppose I need to invest in some kind of leveling EQ that I could put right at the board and adjust to get the bass sounding OK out of the FOH arrangement, then spend time on the FOH as my "amp" to get reasonable sound; but I feel like I'm just putting perfume on a pig.
yeah, a pig that is strapped to a cart that's before the horse, and also filled with apples and oranges
the PA speaker is not
supposed to sound like your bass amp does when you're standing next to it! by that logic, each PA stack should also have a 4x12 guitar cab in it to reproduce the sound your guitar player hears standing next to
his cab.
what should happen is that the
entire PA, from horns to subs, combines to create the sound of the
entire band, evenly and clearly, to everyone in the room. the better the PA, band, soundguy, and room, the closer you get to that goal.
also, that "leveling EQ" is already out there; it's called the channel strip EQ, and "adjusting to get the bass sounding ok out of the FOH arrangement" is a fair description of a soundman's
job.
the idea of you going back there to try and get a FOH stack that's far away from you to sound like your rig when standing next to it, with no regard to everything else that has to also sound good through it at the same time, is just loony.
I'm just saying I personally wouldn't select a Peavey SP3 sitting on top of a Carvin bass bin as my "rig" of choice.
that would be pretty hateful to stand next to on stage, wouldn't it?
by the same token, a bunch of svt cabinets would be pretty worthless as PA subs. these are completely different kinds of speakers for completely different applications. a properly deployed PA rig combines to give a reasonably even output full bandwidth, both above and below what your bass rig likely puts out, and
project it over some distance.
if your tone is together (via mic, DI, whatever), it should take little EQ to make it sound good (and like you) through that good system.
