OK so as promised here's a write up of how I set up the Pet.
Today I soldered all the wiring with my son's help. It's a tricky job and he was great at holding some of the small Piezo wires using a pair of tweezers - they also act as a good heat sink.
First, after screwing the neck to the body - not too tightly, I want to check that the neck is sitting straight in the pocket. I use really cheap strings (80p a set) to do the initial set up when a guitar is at this stage. I used the two E's and eyeballed them to check that they were running parallel with the edge of the neck - when I was happy I tightened all 6 neck screws - please do not over tighten - it is can be bad for a guitar. Also I have not yet polished the guitar as I am touching it so much during set up, it would be a waste of time.
I'm using 2 springs at this stage of the set up and I have also temporarily "chocked" the trem block using a pencil eraser.
At this stage you have to ensure that the trem plate on the front of the guitar is flush and parallel to the body. I use and old 6 inch ruler to help me with this.
At this stage I've brought the E's up to pitch. I slackened the truss road when I took the guitar apart, so now I've now started to tighten the rod just a bit to compensate for string tension.
I'll now add all the strings and whilst doing so, I'll keep checking the trem plate on the fromt of the guitar to keep it parallel - if the plate starts coming up, I'll add the third spring/screw the claw in a bit.
Ok - so I've strung it, brought it up to pitch at the same time added the 3 rd SPRING (the pencil eraser wasn't so good as it started falling apart!) and adjusted the claw so that the trem plate is flush/parallel to the body.
It plays err ok but heck I haven't checked the neck relief by putting a capo on the first fret then fretting at the 12the fret and seeing if I can press the strings to any of the frets around fret 7, I haven't checked the string height at the 12 th fret using feeler guages - but it's getting there. Gonna see if all the electrics work have a play on it and let it settle in overnight. More pictures tomorrow.
