Well, it turned out pretty good all things considered.
I spent a great deal of the day making sure the unit was charged. Then I get to the show and pull it out and it somehow powered up and the battery was drained. So I had to get an extension cord and keep it charging all night. It even came unhooked from the charger at some point in the first set so it was kind of a Murphy's Law thing for a while.
Once I got it duct taped to a wall about 7.5 ft high and got the levels down to 0 - It worked pretty well. I suppose I can't compare it to if I had better mic's going and all that, but I wasn't disappointed with the results at all.
Let me put it to you this way, we run our own sound and have the board on stage with us so we lack the luxury of having a soundguy work through those issues for us.
I was able to pick up every instrument. We didn't mic the guitars and at times they were distant, but I could still hear them and could hear them well most of the time.
So I was only able to salvage about a set of material, but that's better than nothin.
Thanks for all the help - it came in handy!
