The most important element in bass is the really low frequency range aka “The Sub”.
Use higeher frequency sounds on your bass (by using Eq or adding layers of sound) to give it more appeal. However if the bottom end starts to fade away because of this, don’t try to Eq it back. Just add a simple sine wave sound layer under it and play the same notes on a lower octave.
This ensures that you will always have bass on all notes.
