Happy to help.  Good hunting.

Lots of ground hum with no sound in a passive instrument: The first place to look is whether or not the circuit is completed with proper grounding. If it isn't grounded then all the components are kinda acting like an aerial to noise. If the noise goes away when you turn the volume down then its between the pickups and ground, if the noise stays no matter what you do with the volume then check the ground to the volume control and to the socket.

Grab a cheap multimeter to test with - I got one for £5 just for chucking around.

Thanks Dood. 

Turns out I had missed out one arm to pot solder.... call it wood for the trees.

I've got to do a review on the charval as there is an obvious grounding issue but the wiring looks fine so I'm thinking this is linked to the poor shielding spray that is tripping it. 

I may add an extra layer of body to jack for grounding as this is split from the bridge and body cavity to the glock pre-amp. 

Last time I ever buy Fender. Sick of it now. 😒 

I "think" so but haven't sized them up.  Black control plate but dunno if fleabay ones are any good. Alot of money for plastic as I'm going passive.   It's a good headache 

Not so sure about the Wilkinson tuners as they have a rather large mounting plate and the headstock is quite petite. The G tuner might bugger you up due to the way it sits, maybe.

The own brand one`s that Northwest Guitars sell are decent tuners and come in a choice of colours and r/h, l/h.

I'd be checking the location of the screw holes on the base plate too, rather than turning the headstock into Swiss cheese...
