Make sure that your kick has a perfect length and doesn’t interfere with the bass. Simply using fades can help a lot in getting the best interaction between both.

If you use a long kick, tuning it to the key of your track will help in this matter. If you have a long bass, use a short kick and vice versa.

If both your kick and bass play together, make sure the bass hits quieter by using velocity.

By doing this in addition to sidechaining, you ensure to carve enough room for your kick to cut through.

A compressor changes its sound depending on the signal that is fed into it, while volume shapers are more consistent and have the exact same ducking curve every time it gets triggered.

In a nutshell, a volume shaper produces a much cleaner and constant sound while compressors are signal-dependant. Picking the right option is important to get a strong and clean low end.

If you produce EDM, chances are you don’t need a lot of dynamic in the low end: Most EDM tracks low end are quite heavily compressed, don’t be afraid to compress your lows quite a lot.

Done properly, multiband compression can drastically improve your bass presence and consistency.

Analog EQs can be a bit harder to use since most feature fixed frequency bands and no spectrum display, which means you’ll have to use your ears more than with a digital EQ.

However, with some practice you will notice that good emulations often help to achieve warmer and tighter sounding bass.

Group processing is what glues instruments together: Processing multiple bass sounds together can help a lot in this matter.

If you feel like your kick and bass are not well glued together, try processing both in a group/bus: A few dBs of compression can go a long way to tighten your low end for instance.
