O8 - I agree with your statement, but need to add a "footnote". Solo acts would never have gotten a chance if it weren't for the loud, rude, behavior of many bands over the years. I've had bands too, and it was always tough to find players that thought like me, or had my work ethics.
I was forced into solo work, and I still am in copetition with 5 piece bands and larger. I play weddings for $600 - $100 as a solo and I regualrly work clubs that feature loud, rock and blues bands.
It's NOT the gear at all. It's the profession .... and the professional. Doesn't make a bit of difference how many hunks are on stage .... most of the time.
( there is a certain "look" that some head counters need, but for the most part - it's quality, and NOT quantity. )
