The first console in Eddie Van Halen's 5150 home studio was designed by Bill Putnam: https://en.wikipedia.org/wiki/Bill_Putnam. The studio was inside a homemade Faraday cage due to a nearby AM station.
Another fascinating pop music anecdote, and another connection with Amateur Radio ... Also from the cited wiki page for Bill Putnam, "Putnam's interest in music began in this period, and his flair for electronics started when he was in the Boy Scouts working toward a 'wireless' merit badge. At thirteen, he tried and failed (!) to become a licensed Ham operator but at fifteen he succeeded, earning a Class B Call sign WA9PUK." Glad the young Scout persisted!
