I put some new pots in my passive PJ bass yesterday. First things first, it is not shielded, so I am used to hum. After a few hiccups I got it working and it sounds great. The only issue is there is more hum than before. I am running a volume for each, no tone control, with 500k pots. Just curious if, other than shielding, I may need to look at the wiring again to reduce the hum. Shielding is my next project, but for now it was pots and a new jack. Any thoughts are appreciated. And I can post some pics later if that would help, but it's the standard PJ set up.
