I was wondering if the same exists in the world of the great bassists...?

I'd say the same exists in the world of whatever-you-can-imagine!
Take any speaker: he can have a "shocking technique", as you put it, 150,000 words to his vocabulary, a "perfect" grammar and syntax, etc. Does it prevent him from talking... nonsense. It doesn't enable him to make his point through, let alone "moving" his/her audience. It's so obvious I'm sure you've got hundreds of examples coming to your mind.
Listening to others instead of speaking all the time, trying to "tune" with them, etc. could be the beginning of an idea, nope?
In any field, be it music or martial arts or whatever, IMHO, if you want to become a "master" or what you call great, I think the stages are the same: learn the technique, forget the technique, forget yourself (meaning your ego, of course). What's the hardest for you?
