Playing bass with a pick is a lot like playing bass with fingers. If you play towards the fingerboard you are going to have a cleaner, more bassy tone. Where as if you play toward the bridge you are going to have a more nasal, highs and mids emphasized tone. A'la Jaco. Unless you're trying to play the bass like a guitar, with a gentle strum of the pick which gives you no attack tone no matter where your pick strikes string.
I do agree with what you mean, It's all in the attack. That's why John Entwistle will go down as one of the best bassists evar. Don't know him? Youtube The Who. If you want to see a progression of his fingerstyle technique listen to a Victor Wooten bassline. http://www.youtube.com/watch?v=dqLbemgstQA
The tone Victor achieves in this song is just amazing. All done with fingers and varying attack, and a heap of talent (forgive his rapping, the studio version is so much more tasty).
I also never use a pick. If I want a calm mellow tone I use the pads of my fingers between the neck pickup and the fingerboard. If I want a bright percussive sound I use the tips of my fingers with a strong anchor and a powerful strike. I do so by the bridge if I want to cut the mix and by the board if I want a rattly "could be slapped?" percussive tone. If I want the "pick tone" I just use my index finger nail.
I'd really not like to argue bass online. It is the second best thing I do in life next to breathing, and like breathing I can't accurately express how to do it online.
