Bass sound to guitar

If you are playing does the bass player need to be Queiter, louder, or the same volume as the guitarest??

That balance shifts around according to which instrument(s) have the melody line in each section of the song.

So does that mean u would have to change the volume on the board?

If the players interact with each other the way they should, they'll do that for themselves. The soundman should be free to concentrate on the overall sound, and killing any microphone feedback.

I like to have it at least the same volume, maybe just a bit softer, because the bass carries the song.Its the drive.

I think it's a good idea keeping the volume pretty even, and then the players can adjust as needed. For example, it doesn't take much effort to go from soft fingering that's barely noticable to raging slapfunk madness on a bass.

A general rule of thumb I use (which may or may not work for you) is the bass should be loud enough in relation to everything to be heard clearly but not loud enough to drown anything out. It also depends on the skill of the bass player and the guitarist, and it depends on what style of music you're playing, and it depends on the guitar's tone. For example, if you like playing with your upper mids cranked it might be a good idea to give the bass a little boost to balance it.
