Yes, I just saw that on your FB. Cool story indeed. And yes, I can totally see MK doing this, but he would not advertise it, so chances are we'd never know
If some 14 year old kid emailed PCM to say that they had built a red strat like MK's, would they arrange for him to come backstage? Maybe, but probably only if he had cancer (cynical, but likely).
Would MK famous for being a stickler for detail, then take a guitar he has never played before, the wiring of which could be dodgy and cut out at any time, and use it live?
Never in a million years. No chance.
