Well, this is where studying vocabulary comes into play.
You should be learning other bassist's bass lines, solos and grooves - then, (and this is the important bit!) learning which arpeggio or scale they are related to. This gives you instant insight into how other players are using arpeggios and scales to make real music.
You've heard that transcription is important? Well, this is why.
We should be constantly studying how other players are using vocabulary within there playing - and actively absorbing that vocabulary into own own.
Ultimately, this is what will give you your own sound in the future."
