Pickup Screw Static

[AccolaStudios]

After installing a new preamp, I noticed that touching the height screws on my bridge pickup results in a crackling, static noise. All wires appear to be secure and I've rubbed down the screws with a dryer sheet to no avail. Any ideas?

They aren't grounded. Put some copper foil in the pickup cavity and ground it, and make sure the screws touch it.

THAT's the fix...
