See - Just with a quick look at your Profile Vincent I find we have something in common besides trains. I spent 10 years operating a Pro-Audio company doing sound reinforcement for bands and commercial venues. Now, 30+ years later one of the companies I work for bought a bar with a house sound system. I’m now the resident sound techie 
I have been a musician since I was 12 years old (Bass player) then 5-years ago I needed to make some extra money to pay some bills so I quit playing and started renting my PA system (s) out to local bands.
It is pure weekend warrior grunge work, just working the local bar scene but it did help pay off a lot of debt that I fell into (divorce).
I have worked about 70-80 shows a year, but this year I am cutting way back. Just working with a couple of bands in the better/easier venues. This will give me more time to relax and build my new outdoor railroad this summer!
ProAudio is fun, I have learned a lot…especially everything I was doing wrong, well most of it! Hopefully someday I will return to actually playing again though, I do miss it.
