I use walking bass a lot with swing tunes----so anything that improves that style, I’m in favor of. I’ve made this point before-----often with a walking bass line, when you get to the end of a chorus in the key of F (or any other key), the bass doesn’t play the F, which my ear wants to hear. It plays an interval note in the chord, but not the root note, which is very noticeable. And, I check everything to play the “simple” version, of whatever it is. Also, with the bass line on up-jazz tunes, the walking bass will go really high in the upper register, which doesn’t sound right, when you want it to stay low. Regenerating the part helps some times.
