You could also enhance the mids between 800Hz to 1.2KHz, where the fretless mwahh (in the Jaco's kind of tone way) and note articulation sounds. Mudness (is this a word???) may lie a little lower, between 200~450Hz, but you must be wise to not thin your tone too much cuting your bass energie here (this is also where tone's body is felt). The low mids between 250Hz to 120Hz can thicken your tone and help to hear the bass on tiny speakers. The structure or deepness (not the fat) lies on lows below 120Hz and a B string reaches 31Hz.
All those frequencies are just a suggestion to you explore, but you must hear how they work for your bass and with your bandmates, too. Because each of us has our own exclusive tone in mind and you know that mixing also means choosing which frequency we will have to dismiss to other voices be heard. An Eq will affect frequencies above and below those centers (how much depending on its Q setting) so there will be always a overlapping happening there. And, as you are recording direct, check how you sound at engineer's seat to be sure you're not equalizing your bass onboard preamp wrong, based upon how it sounds in front of the amp inside the studio (we should assume that monitors must sound truer than a cabinet).
