It took me a few nights of copper taping cavities, checking the diagram, soldering, rechecking the diagram, soldering some more and then a little bit more checking, holding the diagram upside down and giving myself a fright and then the relief when I figured I was doing it right in the first place etc.... and now it's alive!! Everything works as it should - I chucked two E strings on it and checked the pots and the switch and then jammed "Whole Lotta Love" for its first tune! It even gave me an epic pinch harmonic on the G when I was mucking about with it. I have to admit, for a kit guitar it sounds pretty damn good! No static, no unwanted noise, no crackles. I just all worked as it should and it sounded great. Very happy! Time for a bit of work on the frets and neck and then finishing assembly.
