Some shocking revelations about building safety here, y'all.

If you're renters, ask your landlord what's zap with that.

. . . I'll see myself out.

This is one of those threads where it would really help for any of us to actually be in the room and play the guitar.

A *certain* amount of noise when not touching the strings/bridge is indeed normal on a true single coil, but there's a big big difference between "normal" and how much noise you get when something's not working correctly in the wiring.

Having had wiring fail in a Tele I can tell the difference between normal and too much noise when touching/not touching the strings.

The Ultra though has humbucking pickups. Fender can call them noiseless but what they are is realistically humbuckers with the 2nd coil out of the field of the strings. That guitar should be dead quiet and we shouldn't really be having this conversation. The wiring should be flawless since it's one of their most expensive production guitars. It should have every trick in the book (shielded wire to the jack, etc..) to reduce noise. No point not doing every single one of those non-vintage improvements since the buyer has already bought into non-traditional pickups and a non-traditional fretboard.

Also the shielding paint shouldn't really be that critical in this guitar because again, it's got humbucking pickups. It should be pretty darn quiet.

The first place to start would be to print out the schematic from the Fender website and open the guitar up and verify everything is correct and start looking for poor solder joints.

I had a similar problem with an ESP LTD Viper fitted with ESP noiseless P90 pickups. The neck pickup buzzed like crazy unless my fingers touched the strings. The problem was caused by the shielding paint in the neck pickup cavity not making continuity with ground. The bridge pickup didn't exhibit the same problem because the shielding paint was making continuity with ground via connection to the bridge. I connected a wire from the neck pickup ground side to the cavity shielding paint and the result was quiet as a mouse (which is a minor miracle for a P90 equipped guitar).
