Our set went pretty well, with the exception that our drummer had trouble hearing the vocals and my guitar in his monitor and as a result cut several songs short. We all more or less caught the gaffes, but it was still a bit of a pain.
The guitar cabs were mic'd, but I'd thought I'd taken the extra precaution of angling my cab towards the drummer. However, the pics show different, it's possible that the angle of the amp was changed (it's on casters) by someone moving it to get around it or something. Lesson learned-- at that place make sure guitar cab is positioned correctly so drummer can hear.
