Warwick Corvette SS tinkering

* A Warwick Corvette SS came in for a setup, fretwire + fretboard clean, some wiring issues were solved, and also installed a new tuning key because the old one broke off. Also had to take off the brass nut which was loose and re-file the base of the neck and reglue the nut back.
Had to do some rust removal on some screws (besides taking aparat the whole bridge and cleaning stuff)
