These include EQ and compression which are the two you will primarily use, but also things like amp simulation which can help to add realism and power to your tracks. If you’re looking to record your own bass parts you can do that live as well of course, and whichever route you take, there are plenty of tools onboard to help you get a bigger, fuller bass sound.
If you’re after a more realistic bass sound for your productions you could look at a specialised plug-in like Spectrasonics’ Trilian or one of the many Kontakt-based electric basses from Native Instruments, either of which would do a better job than the simple BooBass that comes with FL Studio.
