Boosting Bass for a Bass Track is something that must be done with extreme care and must be done without "muddying up" the overall sound. That alone can make for huge problems, as the two are mutually exclusive.

When EQing, often is the case that OPPOSITES apply.

For example, if you need more definition on a bass track, that actually comes from the highs and not the lows. This is because the things like the beginning of the pluck of the string is what defines the beginning of the bass note, not the bottom end of the spectrum at all. Those "pickmarks" are important, and regardless of whether the bass is plucked with a pick or with the human thumb or fingers, they can do the most for allowing our limited human hearing to be able to find those all important note initiations. This is typically going to be somewhere around the 4K to 6K region of your equalizer.

Rather than use EQ, or EQ by itself, I think you will find a better way to emphasize your resonant bass by using the Audio Compressor plugin. Compressor first in the chain, followed by the EQ is a nice way to work here. Avoid overboosting bottom end, and by all means check your work on as many different systems as you can before releasing it, you may have to go back, Jack and do it again if it is boosted too much.
