Hey, Mike, your description of your son as an Instrument Tech (Musical instruments) makes me laugh. Not at your son, but because when my youngest daughter had to tell her class what her father did and she told them I was an instrument tech, they wanted me to come by and tell them about working on guitars and such. I had to send a note explaing that I worked on industrial instrumentation, not musical instruments. The guys in the shop i retired from would get a kick out of this because they have all been asked about musical instruments at one time or another
