As one of 3 bass players at our church, I know what the bass in the congregation sounds like. I also get a board recording of each practice we have, so I know what it sounds like there.
I used to bring a board, usually with compression, bass chorus, and other pedals (pitch shift, etc). But any and all effects just were lost in the room and in the mix.
So I just plug in. We use a programmable Sansamp, but the others use my preset and a GKMB115 for a monitor, plus Avioms for everyone. I use a Line 6 5 string Variax, and do change models a lot, including using the 8 and 12 string models. But that's just for me, as no one in the audience/congregation hears anything but basic low end bass. I use ear buds, and the Aviom is pretty compressed with more high end than is heard in the room. My use of compression sounds doubly compressed in my ears, so no compression for me. Any noise is loud in the Aviom and if I hear noise, so will everyone else.
Clean and no noise. Aside from that, my job is to play well and enhance what is being played and experienced by the others.
