Another how do I get this sound thread

I kind of know how to achieve thump, growl, mwah, slap and so on. But, what I'm looking for is purrr. Listened to sound clips for different FX, strings, different style of bass configurations but can't find it. Some examples would be songs on Ray Charles last album. Genius Loves Company. I have "Do I Ever Cross Your mind" with Bonnie Raitt playing right now and that bass is purring. Kind of think it may be achieved with studio effects.

You can get this sound by asking in the Bass, Amps, Effects or Technique forums. Here we only talk about modes and the virtues of tab.
