Help with static issue on pots & metal parts, please

My partscaster had some Bareknuckle Flat 50s pickups wired to a 4 way switch fitted by its last owner. It sounds great but when you're not touching the strings there's a lot of static coming through the tone & volume knobs when touched and a fair bit when touching the bridge. I don't mind a bit of noise but it sounds like it's not wired quite right. I'm no solderer but I'd rather avoid the £50 fee for a rewiring set up if possible. Should I try WD40 or something on the pots first? They don't crackle when turned. Any help appreciated.

Sounds like a grounding problem. Hard to fix without soldering.

My advice: Use the £50 on some soldering equipment instead, and teach yourself a new and very useful skill that will save you many £50s for the rest of your life.

Learning the basics (what you need) of soldering only takes an evening or two with the iron and some instructions. (And for instructions, you have the Internet.)

Actually, you should be able to get equipped for much less than £50. What you need is a soldering iron, solder, some flux fluid or grease, a solder pump (for solder removal), a pair of thin/small pliers. And yeah, buy a multimeter too, but then you're probably approaching the £50 mark.

Thanks - I did solder an amp reverb connection once successfully so perhaps I need to take the plunge... You're right about saving money in the long run.

Try hooking up a length of wire between the current ground points to see if
helps.

Is it a static hum or just lighter static? You could spray the switch areas
through the plate opening and move switch back in forth just to see if there.

No harm in eliminating the minors prior to addressing the majors.

Light static rather than hum. Will get some Servisol or similar and see if it helps...

Check the hum out in several places around the house on different electrical outlets. Could be one home circuit is not well-grounded. If this doesn't fix it, then I'd start looking at grounding problems.

It's definitely worse upstairs but the house is only 10 years old so the wiring should be ok. If I play the amp through battery powered amp, should any static or hum disappear?!
