Al Heeley, I'm taking my hat off for you, you're really into it as I can see and judging by the look and your knowledge of guitar building I'm sure these guitars have a brilliant sound.
I had only one project, a museum piece Vaccaro Custom guitar with V-shape head, single-double pickup layout, volume/tone pots, pickup selector and a special tone selector for extra juice.
It was a present from a well-known rockstar and producer back in the days, but god knows what happened to the guitar! It was prime quality material and electronics but it was poorly built and maintained.
The nut was too high causing the false fret to become useless, the bridge was too far back even if I turned the pegs all the way up causing it to sound out of tune all the time. And it had alot of minor bruises and loose screws.
That is why I decided to fix it up and right now, it's perfect!
Using all pickups makes it sound incredibly full and warm, almost acoustic, while using only the double pickups makes it sound like a strat wich is awesome with overdrive.
All the work and money spent was totally worth what I got back, even more because the guitar was a gift.
