I really like the lipstick singles sound. It also has to do with where they are positioned, as the neck pu is closer to the neck than a Jazz bass. Bridge pu is in a similar location to a Jazz. And stacked V/T V/T pots. Love both buckers and singles but the lipsticks are very mid-rangy which works for me as a palm-muting pick-player. That and the wider distance between pu's gives a more scooped sound that is signature Dano. You hear it clearly on "Wichita Lineman" by Glen Campbell's bass player. I dial the amp for bass, and the bass delivers the mids. Also for these vintage basses - unless they were parts builds, I restore them to as stock as possible.
I've posted this here before - but it's such a beautiful song it's always worth another listen.
