regarding the bass on recordings:
producers don't think about 'a great tone for the bass instrument' (unless the tune is starring the bassist...even then....).
you cats who are chasing tones, and then insisting on your 'tone creation' for all other applications are not living in the real world of recording! on any recording (i.e., e.g., 'genre'), the bass tone is a blend of "what serves the mix/production" + "what can we get away with" + "what tone is acceptable"(in the mix) + yada yada...and most of the time it's a 'neutral' tone setting which is being recorded because that allows the engineer/producer to "take it where they want it" when it's time to make a hit record(ing).
best to re-read a few of the posts above. and be prepared to follow the advice/counsel of the engineer/producer in the studio: they have bigger fish to fry than accommodating your version of "but that's the tone i like."
if you go to a real studio = you will not be in control of your tone!
isolated bass tracks: some may very well be 'corrupted' by the isolation process to, say, youtube, but: all of the tracks i've heard are great representations of the real world of recording!
