Voxy baby now works!

I had a D'oh moment last night.

It's all very well wiring everything to an earth bus rail, but that rail STILL needs to be connected to the electrical earth to function.

There's a dud cap in there too - waggling it produced various degrees of buzzing noise - but replacement is a simple job. There are a couple of further tweaks that are needed, but they should be quite straight forward. I need to remove the 'character' pot (variable 1st gain stage bias) and replace it with something to a fixed value resistor. I'll probably also do a mid and treble boost mod too.
