Joe doesn't seem to own a stingray bass. https://www.youtube.com/watch?v=d5K3UgrPdbQ A Music Man here in this video is also a Sterling 4 Classic. Stingray 4 basses have control plates.

In the video we can see Joe playing an electric bass in an upright position. When the camera pans over him, we can clearly see the SX logo on the bass, along with some additional writing along the headstock. I would tend to believe the writing says Vintage Series. It is also very clearly a natural finish, the body probably is made of ash.

In this Beastly video Joe can be seen playing the Pino Palladino signature bass.

The Joe Dart artist series signature bass is perfect for players who love simplified controls with a rich passive tone. The Dart bass features a lightweight ash body, 22 stainless steel frets, one humbucking pickup, and one volume control for a distinguished funky low-end punch and attack you won't find on other passive basses.

Joe can be seen wearing black wayfarers in almost any music video, live performance, or interview he has ever done. They are clearly part of his mystique but not his power.
