EQ for Bass

Cut below 50Hz and cut above 800Hz.

Compression

8:1 ratio with a reduction down to 12db. To make the bass not as crushed then put two compressors together at around 4:1 ratio and set the thresholds at different levels. The bass will be very compressed but will sound more natural. The bass guitar gets the most compression in the band. The kick drum is the punch of the band, not the bass. The Bass is for the constant low end of the band. 

Melodyne

I use Melodyne (Assistant version) to fix the volume of every note.  The Bass guitar is something that’s an easy fix on pitch and makes it glue together better.
