My preferred approach is for the guitars to back off. My default bass tone has no problems cutting through, and if the guitars/keys lay back and simplify it allows my part to pop more without a dramatic shift in EQ. If you want impact, cut back all the way back to drum and bass. I prefer this method because it keeps my bass tone consistent and it keeps the bass in its own sonic lane.
Beyond that, I use tube amps, so I pluck harder for more dirt, bounce the string off the fret for more attack, and/or pluck closer to the bridge for more midrange.
