A look at the guitar electronics and pickup wiring, the scratchplate/pickguard and the installed killswitch.
A while ago I customised my old Fender Strat copy to a HH configuration. I got myself the Wilkinson Zebra humbuckers which I must add are absolutely brilliant. The wires on the Wilkinson were different colours though so the wiring gave me a headache. I got this sorted and decided to share this diagram as Wilkinson pickups are regularly purchased and I am guessing many people might have the same question I did.
