Well the good news is that sound comes out. And the sounds that do come out are pretty good.
What's puzzling me is that one of the three switch positions is completely silent which would suggest that something has come loose (I'm guessing). So I'll have to take a look at the wires and see what's going on.
Edit: Further testing would suggest my neck pickup wire has come loose.
Edit 2: Earth wire. More soldering for me.
