Advice for upgrading a SUB

[Lai Ti]

I got hold of a Sub today and it's really playable. I love it.

However it's super hot and doesn't sound that versatile, certainly not compared to my Stingrays. I have to keep the volume down, which limits the range of tone available.

Has anyone upgraded the pick ups and/or electronics on a Sub? If so, do you have any advice on what to use.

Complete Seymour Duncan Basslines system. My first MM was already modded with that by its prior owner. Kept it over 10 yrs. Knowing nothing much at the time I just thought it was normal. After all, some builders use various electronics not of their own making.
