As far as the bridge is concerned, the bridge doesn't function as well as the one on my Fender. Maybe I'm expecting too I don't know but I'll change out the bridge as soon as this Corona lockdown is over. I have to mention the pick ups on these CV j's...I've heard they're different from the Chinese CV but these ones offer so much more than you'd expect from a $400 instrument...definitely love these. I might throw on pick up and bridge covers so that it fits my precision's look
I've got a similar bass, a VM70's Squier. I put a Gotoh 201b bridge on it and some Aguilar noiseless pickups and rewired it with full sized pots, plus put the Drop D tuner on. The bridge gave it a *little* more sustain, but didn't change the sound at all. It's cool looking, but if it had cost more than $50 I would have had regrets. I found the drop D works, but found it cumbersome to use, so I soon went to primarily 5 string basses. One of the better mods I made was to my MIM 5 string Jazz; Hipshot USA Ultralite tuners. It cured that bass of neck dive, eliminating a solid 6 ounces (170gm). The stock pickups on the Squier were good, but the Aguilars are much better sounding. The reason I changed them was to minimized hum should I want to change the pickup balance without introducing hum.
