pickup hum

[rafterrick]

I wired my Seymore Duncan JB,bridge; vintage hot stack strat, middle; 59 model, neck with a 5 way blade switch. Guitar sounds great except for a substantial hum. It goes away completely if I touch any metal on the guitar, except for the screws mounting the switch. If I touch it, the hum gets 3x louder. Yikes. What's wrong? Seems like a grounding issue either something is grounded wrong, or something needs to be grounded. Help.
The noise in my guitar is louder thru my tube amp than the solid state ones. It silences completely if the strings, bridge(a thru body Hipshot), volume pot(with all ground wires soldered to it), tone pot CTS DPDT push pull. It only increases if I touch the Switch mounting screws. I am very confident that the bridge ground wire is in place and functioning. I will check the Jack wiring as that sounds like a good possibility. Haste con cause stuff like that.

Ahaa! When I removed the jack plate to check for proper connection, and it was correct, I made sure that the hot tip prong DID NOT contact the conductive paint on the inside of the control cavity when I reinstalled the jack. NO MORE HUM! YEA1

Welcome to the forum!

Yes, it sounds like a grounding issue.

Does it increase/decrease if you touch the strings? That would mean that the bridge needs grounding.

If not really, it may be that the output jack is wired in reverse. Particularly if the pot that has more noise is where the ground wiring goes.

Sounds like a killer set up and a simple issue, hope we can help you resolve it properly.

I am sorry you are having some hum issues. Does this happen in every building you are in? You can take some pics of your wiring and it may help us diagnose what is going on.
