I'll put in my 2 cents...
When I was in the house band in Spain/Tenerife, there would be many instances of the power going out.
I felt strange watching the other members grab acoustic guitars, drums, etc., and I just stood on the sideline. I kept thinking "without 220/240 volts, my experience and musicianship don't mean squat." It was a sobering experience...
I've played fretless in the UK for acoustic artists. I was in the house band and if they wanted a group, that was my job. I would always have someone ask for acoustic bass... Eventually...
Seeing the debate between Ron Carter and Anthony Jackson, plus other various articles on "doublers" made me feel that I should be able to play both. In fact, several famous musicians in the London scene told me "I only use acoustic bass in my bands..."
I slowly, but surely, started to learn Upright bass... Try it, it's a lot of fun...
Don't bother if you don't feel it. It's not for everybody... You could play the Acoustic bass guitar. People will always create an issue, ignore anything regarding music that your heart doesn't lead you to... Also, kudos for helping your friend...
