I am wanting to know how big of a difference an Avalon U5 will make for a live set up in a church. We have a few bass players with passive basses and they pretty much sound like crap going directly into a direct box. I dont have so much of a problem with it being that i dont own anymore basses without onboard preamps. Im looking for a good preamp that the guys dont really need to do to much eq'ing on just so they dont mess around with it all the time(we will leave that to the sound man). I have been searching for a while and always seem to go back to the U5's, any input?
