I assume this vid is pre-Nirvana? ![Grin ;D](https://bassoutpost.com/Smileys/default/grin.gif)
Definitely not an EB-0, sounds more like a freshly strung P, Ric or even Stingray to me.
Not a Stingray, because that has a kind of tone that sets it apart from all other basses out there. My guess is that it was a Spector because it sounds similar to Mike Starr's tone on Alice in Chains' "Would"
This video is from 1990 so yeah, it's pre-nirvana but you can already hear the change in mood in this song, it's not as glammy as Poison or Faster Pussycat, this song already has that darkness that foreshadowed things to come.
