Gents, thank you all for the words of encouragement especially as the yellow should have been stained and ended up solid !
To answer your questions:
Yes the three way switch does make a difference to the tones, some useful and others not so useful.
There are 9 different switchings as well as the tone control so a wide palette of sound is available.
The only thing was that this setup needs three way switches and the kit came with two way ones.
Good old ebay and a 10 day wait brought some of the finest switches from China at a reasonable price.
The yellow is a Halfords (UK motor factors) 'arty' rattlecan spray which is quite bright but also not harsh if that makes sense.
You can buy their stuff or borrow the diagrams, there are also simpler ones on their website.
I made a life size cardboard template, mounted the hardware and then wired it up.
Also bought some 3 and 4 way plug/sockets to help the wiring so I did not have to battle with
a loom for both sides. I thought that getting the hardware in would be a difficult operation.
A bit of thought and planning and it was done in 30 minutes. Phew !
As for playing well, hmmmm... not bad is my answer.
Despite slackening off the truss rod there is a tad too much back bow in the neck which means that the action
is just a bit too high otherwise the strings buzz on frets higher up the neck.
As the higher frets are not likely to be used by me or its new owner I could level those frets flatter but I will press
on with the build of No 2 for now and let the set up of No 1 settle.
I may learn more on No 2 which will help to improve No 1.
Again, thank you for your comments and feedback, always very welcome.
Might put it forward for Geetar of the Month.
Cheers, FB.
