Depending on the genre of music you record, bass is either important or very important to your overall sound.
In many varieties of dance, funk and soul music the bass is very prominent even a lead instrument but maybe played very differently!
To ensure you obtain maximum bass without overpowering the mix, you should employ EQ, Compression and Limiting! Logic Pro offers all the plugins you require to obtain a professional bass tone.
Applying EQ to the bass sound that is most effective for your bass signal apx 80-120hz, this will depend on your sound ie acoustic bass, electric bass, acid synth bass etc…
Compression can be used and applied in accordance with your desired sound, but normally with a fairly high ratio to ensure the signal doesn’t get to loud, attack and release times depend on the style of playing.
For increased control over peaks I would suggest a Limiter as this ensures that a louder bass signal will not clip and therefore distort unpleasantly,
You may want to add some other plug-ins on bass sounds, for example mild amp distortion can add presence to bass as can a little overdrive. Experimentation is key here.
Other areas for experimentation include side-chain compression, Filtering of Synth basses, Layering Bass Sounds, Sub bass plug-ins found in Logic Pro, Pro tools etc…
Finally don’t forget you can’t mix anything properly unless you have neutral monitor speakers, and an acoustically treated room, also if you are mixing dance music, you may have to create test mixes for in-house PA systems to hear your bass response in these systems. With the best will in the world, nearfield monitors can not replicate a club PA!!
