OK here's a really brief summary of what happened at the gig.

I arrived almost two hours before performance time.
Good thing too because it took 1.5 hours to unpack/move, set up the sound system!

Once the system was operating I let the vocalist adjust the settings to her liking (she had a lot of experience performing and mixing).

She removed basically everything (guitar, bass, drums) from the monitors and had just her vocals coming from them.

I could hear everyone but I felt that my guitar was a bit weak at times and should have either boosted the level in the mains or increased my level on my amp or guitar pots.

We didn't have the luxury of doing a sound check before the gig nor of having someone knowledgeable check out the sound from the audience.

We were basically winging it. What it sounded like from the audience was anybody's guess. The audience seemed to enjoy the music so that was nice and people were even dancing at times.

A few audience members came up during the evening to sing some songs with the band and got a good reception from the audience as well.

Overall it seems everyone was happy with the performance but as to what it actually sound like mix-wise?

My biggest lesson though was the work required to set up the sound system. I don't mean the actually mixing. I mean the lugging of the equipment putting everything together. The 2.5 hours setup and tear-down + the renting the equipment loading the car etc. etc.

I have performed many times prior to this, but it had always been simply, guitar and amp into car, unload guitar and amp, re-load guitar and amp, drive home!
