The BEST thing about shooting someone down in a forum as opposed to using a real gun is that no one dies, but everybody gets to learn a thing or two.
IMHO, the best answers given to this topic so far has been 'shut up', in one form or another (go practice and find out for yourself).
Had this thead gone to discuss things like relying on amps, compression, string-type (rounds, flats, hybrids), or even type-of-bass (passive up to 27V-pre), to determine tone via various nuances and styles of attack for bass playing, I'd probably have alot more to say than 'go practice'.
Forgive me if I sound uppety, but debating whether 'tone is in the fingers' or not, is pretty damn elementary, and equivalent to telling a new player to go try the bass for himself instead of asking if there is a pre-fixed formula for choosing basses for individuals.
Have fun, explore and discuss, keep the cycle going, and we'll all have alot more things to inspire us via learning!
