Mike is the head tech, but that doesn't mean he works on every amp he diagnoses or talks with you about. i don't work there, and i'm not 100% on this, but he has to have minions like any other boss man. There is no way a company like that would only have a mike and rich working on amps.Does everyone get Mike B to service their amps? Cause there's other guys that work there you know? I got a guy named Rich Duvall working on my Mark IVb right now at Mesa Boogie. I've sent 3 Boogies in for servicing and I don't think Mike B serviced any of them, but they all turned out great.
