Classic Stingray and bass set up guide

I did an extensive search for this and didn’t really find an answer or thread that had this listed. I recently bought a used 2017 Stingray Classic and it seems the previous owner changed the pickup height as it is now on a tilt. the bass side is much lower than the treble side. I’d like to reset it to factory or suggested specs if possible. Is there any such guide to go over this bass? Thank you for any guidance. Sorry if this has been discussed but I searched until I was blurry eyed.
