Always cut to the chase ;-) Yeah, so far so good. I shielded the cavity, soldered on the ground connection and put it all together tonight. I played just enough notes to test that the wiring was good. It is, and those few notes sounded good, although I have the stock PB strings on it right now. My initial reaction is that is sounded just like a p-bass should. But it's a little distracting not having the setup right. Now that I can see it all works, I'll put on a better set and do the setup. I'll have a better sense of the sound then.
In the meantime, I got a few pics. Garage lighting in the middle of the night, so not the best, but you the idea.
