I call it the four T's: tone, taste, timing and technique. Tone means having a generally pleasant sound on the simplest level, and on a more advanced level means having the right sound for the right situation. Taste as in knowing when to hang back and keep it simple, and when to do something that stands out. Timing is obvious-be able to hit a mark, but also be able to push and pull and generally lock in with the drummer. And technique doesn't necessarily mean crazy shredding, but be comfortable in your playing and know how to get the best possible sounds out of your instrument. Other than that, it's a matter of knowing your role in the band-understanding that you're part of the rhythm section, but you're also the bridge between the melodic and rhythmic aspects of the music. It's about your musical knowledge and skill, but also about your mindset. That to me is a great bassist.
