Yep. Love his playing, one of my favorites. I know he used a Sadowksy J when playing live, but I believe he has used a Stingray in the studio for awhile. Underrated player (IMO)
Yeah. He used the Sadowsky I think on the Creed records. The old stuff may have been an original Jazz bass. Regardless the producer used the Sansamp bass driver on those old records. That was a big part of the sound, and I was told this firsthand. Not to derail, but I thought you may find that somewhat interesting.
To me the stingray is everything the Jazz is not - awesome slap tone but still is very mid focused if you play fingerstyle. I really enjoy the modern, burpy response of it. An amazing Ray tone is Scofield's Loud Jazz album - just penultimate Ray tone, IMO.
