No company in the world would pay a repair man a million dollars. Probably more likely that Gibson just stop accepting out of warranty repairs, or mods of any kind.
Mike has also got to be around the same age as Randall, I’m sure he wouldn’t mind retiring. And if not, he can keep doing repairs without Mesa/gibson. I recall someone here saying when they got their recto modded to rev c specs they were billed by Mike directly rather than though Mesa.
