I didn't change the POTS when I changed pickups on my LP because they worked just fine, but since I don't have a guitar tech's experience/knowledge, I kept wondering if it would have improved the sound a lot if I had changed them.
I also assumed that a SD or better branded POT would work better than a stock Epiphone POT but didn't want to invest in it if the sound difference was minimal.
Sounds like the consensus is that it won't make a big difference and really no need to fix it if it's not broken, which I can agree with since I'm not performing and just playing for fun at home.
But I do like and appreciate hearing from all of you with more tech knowledge; it's giving me a much better understanding of the instrument and it's components outside of just playing it.
