one thing that should be mentionioned is how the bass was recorded; di or amp. since the amp usually has some compression going on, you would need less compression in the mix than if you plug the bass right in and use plugins. i usually compress the bass quite a bit and have never done volume automation on bass ever, i usually just find good compressor/limiter settings and leave it, but i'm also lazy
perhaps i'll upload a bass track on here i did with a sansamp recently for a punk band.
I usually limit anything that pumps the master bus too hard, kinda like snipping it at the bud, rather than dealing with it on the 2 buss. sometimes palm mutes need it, sometimes (usually) the snare needs it, and sometimes bass needs it.
