after about a year of trying to make the perfect bass, its really all about the sample you choose, compression, distortion, filters, and EQ. Distortion gives color and character to the bass, kinda adds that rumble. Compressor helps you control the volume of the kick and the characteristics of the volume. Filters, this is where you can really personalize your bass. hp filters can cut off the super low frequencies that mud up the bass, make it too loud/distorted. You can even high pass through the critical frequencies (30, 40, 60, 80) to get different weird effects, most trap bounce 808s dont have so much sub (30-40) prescense because it can be very overbearing and its hard to make a clean mix with a ton of subbass. With a lowpass you can make the bass sound cleaner and deeper, give it a try yourself lowpassing subbass can make a huge difference not only for how the bass sounds but also for how it works in the mix. But if you want to make perfect bass like some lex lugar/mike will shyt, its all about knowing HOW to use the effects.
I cant really tell you my methods for making a nice bass, partially because its all about the song. Sometimes you put more distortion on if its not a serious sounding production. If you want something very professional and clean sounding, its all about EQ, filters, and compression with some distortion. I bolded and underlined EQ at the top because thats the most important part. doing a wide boost of all low frequencies is not a good idea generally, as some of the ranges have sweetspots while other parts just sound bad. Mess around with EQing bass in the lower frequencies between 30-90. Youll figure out how different frequencies make it sound differently. I could tell you my general bass mixing strategy, but honestly it varies so much from track to track. Also i think it would be better for you to learn more about the dynamics behind bass instead of just using some predetermined strategy for mixing every bass.
