Need help with an old EMG set up.

[Ascension]

It's in the Washburn USA mutt. System is an old hard-wired 85 bridge with a H60A in the neck from the late 90s. In this particular guitar, it sounds fantastic. More of a jazz or clean guitar and very unique in the tones. I would like to keep it as is but for one thing.
The issue is when I run the volume above half way I get noise. Not a ground buzz but a hum and at full volume it seems very hot with some distortion. Have cleaned everything twice, dropped in a new Lithium 9 volt and went over every connection plus reflowed a couple with no change.
Anybody here have any ideas. Bad volume pot or tone cap maybe? Doesn't change much depending on pickup selection and the preamps are in the actual pickup on the EMG set. I'm stumped for now so a little help and insight if you have it would be appreciated! Will try and find a EMG site if I have to but wanted to start here.

Try with the pots disconnected.

Never thought of that will do!

Nothing to do with your hum, but I would personally put a regular alkaline 9v battery instead of lithium. The reason being that alkaline is discharging more slowly and you will hear it, so you could change it before it cuts abruptly like lithium. Or have a routine to change your lithium battery every X months to prevent the abrupt cut. At home it's not a problem though

Has everything to do with the humm. I came over to post that I solved the problem by swapping to an Eveready alkaline Energizer from the lithium version. Instantly it was quiet so??

Any digital effects in the line? Some of them can't deal with hot active pups.

Very good to know, thanks.

Only in the loop but the noise was there with the loop bypassed.
