:( I've already tried all that. Have even gone through and done most of the joints again just to make sure there isn't a dry joint or anything :/Quote:

When I used a metal object (pliers etc) all the control functions worked properly. Volume up down, pick up selector, tone... It all workedQuote:

I'm guessing that it could be that the bridge needs to be connected to a ground wire that connects to a suitable ground point on one of the pots, try re-installing the pickups and controls, etc in your guitar then see if you can get your husband to check with a multimeter to see if there's continuity between the bridge and the sleeve connection of the output jack, if there's no continuity then that's most likely what's causing the hum.
How loud is the hum in comparison to the sound you get when tapping the pickups?, is it a fairly loud hum, or a soft background hum?
I know from experience just how frustrating it can be to try and find the cause of a fault in electrical equipment, just keep persevering and eventually you'll have a win.
Hope that helps.
Hey Doc, no it is humming in the cardboard template. If you check out my video (below) you will hear the sound it is making.Quote:

@Shazzrandom: I'm not an expert in guitar cabling, but you seem to have a lot of long unshielded cable runs.
To the more knowledgeable guys, could these be the issue, picking up noise from TV, lights, etc?
As an electrical engineer who hasn't touched real electrical engineering for 20 years it all looks like a lot if nice antennas.
Shazz, were you in the same conditions when you tested it clean the first time? Ie. did you have less electrical devices on around you and were you testing in the same place in your house?

Shazz on the test video the circuit isn't earthed to anything so it probably will buzz. Some of the solder is caked on the back of the pots so I am thinking one of the pots aren't earthed properly and not making full contact with a pot casing.
Double check that no earth points on pots have come apart from the casing
Otherwise re-do the soldering with braided wire might be the best option.
Also Fred has made a good point about any electrical devices nearby could be causing interference.
If I build a hollow body in the future I will only use braided wire from experience from other buillders.
That white wire not connected to anything I presume is the bridge post earth wire. Try exposing some bare wire and hold it with your fingers to see if that earths the circuit and stops the hum

Hey Shazz,
Personally, I would file the loom in the bin and start again but with better quality wire and pots.
I reckon your problem is a dodgy pot?.. Thoughts guys?
