I did ~ I had 4 Units on the road in the late 60's.
I also had one of the very few McIntosh Amplifiers in the UK and the nearest Service Agent was in Luxembourg, when my arm was twisted I was known to do maintenance work on them and carried spares. That's how I got to work with the Dead and also to meet with Bowie and one of the Stones. The Who Tour was through Chris Wolf and his Laser Lighting Company which also linked back to the other two. On the lighting side, I was very much part of the workforce rather than having any technical status, sort of Gofer rather than Groupie.
